Question

a grain silo has a cylinder shape. Is radius is 9 ft , and its height is 42 ft. What is the volume of the silo? use the value 314 for it and round your answer to the nearest whole number. Be sure to include the correct units of your answer

Answer 1

To find the volume, we will use the formula;

V = πr² h

where v is the volume, r is the radius and h is the height

From the question, r = 9 h = 42 and π = 3.14

substitute the values into the equation

V = 3.14 x 9² x 42

= 3.14 x 81 x 42

=10682.28

V≈ 10682 ft³ to the nearest whole number
