Question

If the radius of one of the semicircles is 7 meters, what is the circumference of one of the semicircle? asap 70 Ponits!!!!!!!!!!

10.99 m
21.98 m
87.92 m
43.96 m

Answer 1

The circumference of one of the semicircles is 21.98 m.

Explanation:

The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.

A semicircle is half a circle, therefore the length of the curved part of the circumference of a semicircle is half the circumference of a circle: πr.

Given the radius of one of the semicircles is 7 m and π ≈ 3.14, the circumference of the semicircle is:

⇒ C = 3.14 · 7

⇒ C = 21.98 m

Answer 2

The circumference of one of the semicircles with a radius of 7 meters would be approximately 21.98 meters.

Explanation:

The circumference of a circle can be calculated using the formula:

C = 2πr

where C is the circumference, π (pi) is approximately equal to 3.14, and r is the radius of the circle.

For a semicircle with a radius of 7 meters, the circumference can be calculated as follows: Because the semicircle is a half circle, then:

C = (2πr)/2= 3.14 × 7 = 21.98 meters

So, the circumference of one of the semicircles with a radius of 7 meters would be approximately 21.98 meters.
