Question

find the area of a circle . diameter =30cm . suction
​

Answer 1

Area of Circle = pi * r* r

Diameter = 2* r

Radius = 30/2 = 15 cm

pi = 3.14

Area of circle = 3.14 * 15 *15 = 707.14 cm ^2

Answer 2

Area of Circle = Pi r^2
Diameter = 30cm
Radius = 15 cm
=> 3.14 x 15 x 15
=> 706.5 cm ^3
