Question

A semi-circle shaped rug has a diameter of 5 feet. What is the area of the rug?  (​

Answer 1

Answer:

Area of the semi-circle = 9.8125 feet

Step-by-step explanation:

As I hope you're aware, the formula of the area of a circle is πr², where 'r' represents the radius. We also know that the radius is half of the diameter. So, that means the radius is 2.5 feet.

Using the formula of area, we can say:

Area of circle = 3.14 × 2.5 × 2.5

Area of circle = 3.14 × 6.25 = 19.625 feet

We all also know that a semi-circle is half of the circle. So, its area will always be half! We divide 19.625 feet into two parts, and that will be the area of the semi-circle. Half of 19.625 is 9.8125 feet.

So, the area of the semi-circle is 9.8125 feet.

I hope this helps!!
