Question

Find the area of the circles of following diameters. a) 70 cm b) 56 m c) 49 cm

Answer 1

hope you get the answer

Answer 2

Answer:

a) 70/2 = 35 cm = radius. Area = 2$\pi$r = 2$\pi$(35)

= 2*3.14*35 = 6.28*35 = 219.8 cm.

As for the rest, they should be done the same way too!

Step-by-step explanation:

Formula for finding area of a circle: 2$\pi$r (where r is the radius).

Radius = Diameter/2

$\pi$ ~ 3.14
