The area of this semi-circle with radius is 8831.3 square cm

<h3>How to find the area of this semi-circle with radius?</h3>

The radius is given as:

Radius, r = 75cm.

The area of this semi-circle with radius is calculated as:

A = 0.5 * πr^2

Substitute the known values in the above equation

A = 0.5 * 3.14 * 75^2

Evaluate

A = 8831.3

Hence, the area of this semi-circle with radius is 8831.3 square cm

Find the area of the circle. Round your answer the nearest whole number, if necessary.

mina [271]

Answer:

The area of the circle is 314 in^2.

Step-by-step explanation:

10 inches is the radius.

The formula for the area of a circle is pi times radius squared.

So your equation would be: $A=\pi (10)^2$

10^2 = 100

Then you do $\pi$ or 3.14 times 10 = 314.1592654 or just 314.
