There are 100 centimeters in one meter, so multiply 7 meters by 100 to find out how many centimeters equal 7 meters.
7 * 100 = 700
There are 700 centimeters in 7 meters, so that means:
The goal is 700 centimeters wide.
V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
