Answer:
3.8 meters
Step-by-step explanation:
In order to find the circumference for a circle, we use the formula π(radius)²
The circumference give is 45.84 and the π given is 3.14
All we have to do is to just substitute them.
45.84 = 3.14(radius)²
45.84 / 3.14 = radius²
14.6 = radius²
radius = √14.6
radius = 3.82 ≅ 3.8
Answer:
approx. 7.3 m
Step-by-step explanation:
The formula for the circumference of a circle is s = r·Ф, where r is the radius and Ф is the central angle in radians.
Here C = 45.84 m = 2π·r. Solving for the radius, r, we get:
45.84 m
r = --------------- = 7.299 m, or approx. 7.3 m.
