Question

There are three blades radius 60cm find the area of each blade

Answer 1

Given that,

Radius (r) = 60cm

By using the following formula we are able to find the area of the circle.

I.e., Area = 2 × pie × r^2

We know that, pie = 22/7 or 3.14...

Therefore, by substituting the value of pie,

Area = 2 × 22/7 × 60cm × 60cm

Area = 22/7 × 30cm × 60cm

Area = 22/7 × 1800cm^2

Area = 257. 14.. × 22

Area = 5,657. 08 cm^2
