:: 
Rearrange variables to the left side of the equation: 
Calculate the sum or difference: 
Divide both sides of the equation by the coefficient of variable: 
Cross out the common factor: 
The formula for the volume of a cylinder is pi * r^2 * h and it is equal to 108pi. This makes r^2 = 9 which means r=3
Answer:
Step-by-step explanation:
The range, in a layman language, is a set of values for which f(x) exist. Hence suppose our pre-image is 0-6,and since f(x)=20x+4 ,then
When x=0, f(x)= 4
When x=1, f(x)=24
When x=2, f(x)=44
When x=3, f(x)= 64
When x=4, f(x)=84
When x=5,f(x)=104
When x=6, f(x)=124
Hence the answer is B.
Answer:
72 sq ft.
Step-by-step explanation:
Surface area of Triangular prism=[2*(1/2)*3*4]+(5*5)+(3*5)+(4*5)=12+25+15+20=72 sq ft.
