Question

A grain silo is 175ft by 5ft

What is the volume of grain that could completely fill this silo, rounded to the nearest whole number? Use 22 over 7 for pi.
A) 13,750 ft3
B) 14,012 ft3
C) 262 ft3
D)4,583 ft3

Answer 1

A is the answer

Explanation:

(22/7)=3.142857142857142857143

take 3.142857142857142857143*25= 78.57142857142857

then take 78.57142857142857*175= 13750ft3 cubed

therefore its a so he was right

Answer 2

Use the formula for finding the area of a cylinder - V = (pi)r^2h

Add in the numbers you were given:

V = (22/7) 5^2 (175)

The volume is A) 13,750 ft3
