Mr. Dean has provided you with the following diagram. See attached
Calculate the total cost of the semi-circular driveway.
area = piRsq/2 - pirsq/2
I said R = 30
r=14 and I got area =1105. 84 sqft
How do I calculate the volume ?
I have an answer but I don't get it.
V= 1105. 84 x 10/12 ( I don't get the 12) this is for the excavation.
