Introduction
The Big Circle Problem is a well-liked math problem-solving competitors that challenges college students to resolve complicated circle-related issues. The competitors is designed to check the problem-solving skills of scholars in a enjoyable and interesting approach. On this article, we’ll give you the reply key to a number of the follow issues from the Big Circle Problem.
Downside 1
Within the first drawback, you might be given a circle with a diameter of 12 cm. What’s the circumference of the circle?
Reply: The circumference of the circle might be calculated utilizing the system: Circumference = π x Diameter. Subsequently, the circumference of the circle is 37.68 cm.
Downside 2
Within the second drawback, you might be given a circle with a radius of 5 cm. What’s the space of the circle?
Reply: The world of the circle might be calculated utilizing the system: Space = π x Radius x Radius. Subsequently, the realm of the circle is 78.54 cm².
Downside 3
Within the third drawback, you might be given a circle with a radius of 8 cm. What’s the size of the chord that’s 6 cm away from the middle of the circle?
Reply: To search out the size of the chord, we have to use the Pythagorean theorem. Let the size of the chord be ‘x’. Then, we have now: x² = 8² – 6². Fixing for ‘x’, we get x = 4√7 cm.
Downside 4
Within the fourth drawback, you might be given a circle with a radius of 10 cm. What’s the size of the arc that’s subtended by a central angle of 60 levels?
Reply: The size of the arc might be calculated utilizing the system: Arc Size = (Central Angle/360) x Circumference. Subsequently, the size of the arc is (60/360) x 2π x 10 = 10.47 cm.
Downside 5
Within the fifth drawback, you might be given a circle with a radius of 6 cm. What’s the size of the tangent that’s drawn to the circle from some extent 10 cm away from the middle of the circle?
Reply: To search out the size of the tangent, we have to use the Pythagorean theorem. Let the size of the tangent be ‘x’. Then, we have now: x² = 10² – 6². Fixing for ‘x’, we get x = 8 cm.
Downside 6
Within the sixth drawback, you might be given a circle with a diameter of 20 cm. What’s the size of the phase that’s reduce off by a chord that’s 12 cm away from the middle of the circle?
Reply: To search out the size of the phase, we have to use the Pythagorean theorem. Let the size of the phase be ‘x’. Then, we have now: x² = 20² – 12². Fixing for ‘x’, we get x = 16 cm.
Downside 7
Within the seventh drawback, you might be given a circle with a radius of seven cm. What’s the size of the phase that’s reduce off by a chord that’s 10 cm away from the middle of the circle?
Reply: To search out the size of the phase, we have to use the Pythagorean theorem. Let the size of the phase be ‘x’. Then, we have now: x² = 7² – 5². Fixing for ‘x’, we get x = 4√3 cm.
Downside 8
Within the eighth drawback, you might be given a circle with a radius of 9 cm. What’s the size of the phase that’s reduce off by a chord that’s 8 cm away from the middle of the circle?
Reply: To search out the size of the phase, we have to use the Pythagorean theorem. Let the size of the phase be ‘x’. Then, we have now: x² = 9² – 8². Fixing for ‘x’, we get x = √17 cm.
Downside 9
Within the ninth drawback, you might be given a circle with a diameter of 16 cm. What’s the size of the phase that’s reduce off by a chord that’s 7 cm away from the middle of the circle?
Reply: To search out the size of the phase, we have to use the Pythagorean theorem. Let the size of the phase be ‘x’. Then, we have now: x² = 8² – 7². Fixing for ‘x’, we get x = √15 cm.
Downside 10
Within the tenth drawback, you might be given a circle with a radius of 12 cm. What’s the size of the phase that’s reduce off by a chord that’s 15 cm away from the middle of the circle?
Reply: To search out the size of the phase, we have to use the Pythagorean theorem. Let the size of the phase be ‘x’. Then, we have now: x² = 15² – 12². Fixing for ‘x’, we get x = 9√7 cm.
Conclusion
We hope that this text has helped you to resolve a number of the follow issues from the Big Circle Problem. These issues are designed to check your problem-solving skills and that will help you enhance your math abilities. Hold training and good luck!
