Question

Hi i need help on this circumference question pls

Answer 1

≈ 35,53 m

Explanation:

Given:

∠GCM = 76° (central angle, which is equal to the arc on which it rests on)

arc FG = 7,5 m

Find: C (circumference) - ?

The whole circle forms an angle of 360°

Since we don't know the length of the radius, we can make a proportion to find C:

76° - 7,5 m

360° - C m

Cross-multiply to find C:

`c = (360° * 7.5)/(76°) ≈35.53 \: m`
