Question 301649
Calculate the volume of a cylinder 5 inches high with a diameter of 20 feet.
Convert all units to yards first.
H=5 inches=5in (1 yd/36 in)= 0.167 yd
D=20 ft=20 ft(1 yd/3 ft)= 6.67 yd
Volume of a cylinder is,
{{{V=pi*D^2*H=pi*6.67^2*0.167=23.34}}}
Now you have 23.34 cubic yds of concrete and it costs $45 per cubic yd.
{{{P=23.34*45=1050.34}}}
.
.
.
It will cost $1050.34 for the concrete.
