Question

WORK OUT THE AREA OF EACH CIRCLE USE PI=3.14
A/RADIUS= 3CM
B/RADIUS= 7 M

Answer 1

Answer:

$\boxed{ \bf{\text{Area of a circle} = \pi r^2}}$

A) Radius = 3 cm

⇒ Area = 3.14 × 3 × 3

⇒ Area = 28.26 cm²

B) Radius = 7 m = 700 cm

⇒ Area = 3.14 × 700 × 700

⇒ Area = 1538600 cm²

Hope it helps!

Have a nice day ^_^
