Jack pours cylinder-shaped concrete support bases for bird baths with a radius of 7 inches and a height of 26 inches.What is the volume of one base?
A. 1143.5 in3
B. 1274.0 in3
C. 571.8 in3
D. 4002.4 in3
Volume of a cilinder = Area of bottom * heigth
Area of circle = radius^2* pi
V = r^2*pi*h
V = 49in^2*pi*26in
V ~4002.4 in^3
D is the correct answer
D
[1]
It is 3.14×7^2×26 in ^3
=4002.4 in^3
D is the correct option
To find a volume of a cilinder use this fromula
Area of bottom * heigth
The bottom if cilinder is a circle
Area of circle = radius^2* pi
V = r^2*pi*h
V = 49in^2*pi*26in
V ~4002.4 in^3
D is the answer
