Question

Find the area of the circle with a radius of 15 meters
Find the area of the circle with the radius of 13 decimeters

Answer 1

1)area of the circle = πr²=22/7× 15m×15m = 707.14 m²

2)area of the circle = πr²=22/7×13dm×13dm = 531.14 dm²=5.3114 m²

Answer 2

Step-by-step explanation:

The formula of area of a circle = πr^2

Where r donates the radius

so,

Area of circle r = 15

3.14 × (15)^2

= 706.5 cm^2

2. since A = πr^2

A = π ( 13) ^2

A = 169π

Thus the answer is 169π
