X=45
Answer: x=45
Answer:
8,3*0,25=2,10%(2d.p)
Step-by-step explanation:
V = 576 pi cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
V = pi * (6)^2 * 16
V = pi *36*16
V = 576 pi cm^3
Filling in the given information, you are asked to find "r" from
64π = 4πr²
Dividing by 4π gives
16 = r²
And taking the square root tells you
4 = r
The appropriate choice is ...
C. 4
