Question

Find the area of the circle. Write your solution in terms of and round to the nearest hundredth.

Answer 1

Answer:

A = 25π cm²

In decomal form = 78.5cm²

Step-by-step explanation:

Area of a circle is expressed as;

A = πr²

r is the radius of the circle

Since we are not given the radius. Let us assume that r = 5cm

Substitute into the formula;

A = π(5)²

A = 25π cm²

As a decomal;

A = π(5)²

A = 3.14 * 25

A = 78.5cm²

Note that the radius of the circle was assumed. The same calculation can be employed for any value of the radius
