WebOct 14, 2024 · Exercise: 10.2. In Q.1 to 3, choose the correct option and give justification. 1. From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm. The radius of the circle is. (A) 7 cm. (B) 12 cm. (C) 15 cm. (D) 24.5 cm. WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd. C = 2πr.
