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