Question

The circumference (C) of the base of a grain silo is 160 feet. To the nearest tenth, what is the radius (r) of the silo? (C = 2πr)

A) 18.5 feet
B) 25.5 feet
C) 50.9 feet
D) 64.8 feet

Answer 1

The answer would be 25.5 feet, bc the circumstance is given 160, you plug it in the equation, then divide it by 2 and pi, having r on one side and the answer on the other

Answer 2

Answer: B) 25 feet

Explanation:

The formula to find the circumference of a circle is given by :-

`C=2\pi r`, where r is the radius of the circle. (1)

Given : The circumference (C) of the base of a grain silo is 160 feet.

Then,by using (1), we have

`160=2(3.14)(r)\\\\\Rightarrow\ r=(160)/(2*3.14)\\\\\Rightarrow\ r=25.4777070064approx25.5\text{ feet }`

Hence, the radius (r) of the silo= 25 feet
