Question

The diameter of a semicircle is 2 miles. What is the semicircles perimiter?

Answer 1

The perimeter of the semi circle is gonna be π or 3.14

Explanation:

So we know semi circle

The diameter is 2 so that basically also means the main circle diameter is also 2

we trying to find it’s circumference (perimeter)

We can follow the equation

C=πd

In this case d is 2

So 2π

And since that is full circle, half circle would be π

Answer 2

6.28 (equation for circle perimeter is 2πr)
