Question

Fine the area of a circle with a. Diameter of 15 units. Round your Awnser to the nearest whole.

Answer 1

Given:

Diameter of circle is 15 units.

Required:

We need to find the area of given circle

Explanation:

d is the diameter of triangle but we need r radius

$r=\frac{d}{2}=\frac{15}{2}=7.5\text{ unit}$

Area of circle is

$A=\pi r^2$

substitute the value of r

$A=3.14*7.5*7.5=176.7\approx177\text{ unit}^2$

Final answer:

Area of given circle is 177 square units
