V = volume of a cylinder = Pi*Diameter*depth
144 square inches = 1 square foot
volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet
We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.

V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
Assuming it is 9 INCHES deep, Vol = pi*r2*h = pi*(d2/4)*h = 19113 cubic inches (approx).

To calculate the volume of concrete needed, first find the volume of one hole. The radius is 8 inches (16 inches diameter) and the depth is 30 inches. The volume ( V ) of a cylinder is given by the formula ( V = \pi r^2 h ). Calculating this gives: [ V = \pi \times (8^2) \times 30 = \pi \times 64 \times 30 \approx 6028.32 \text{ cubic inches} ] For 40 holes, the total volume is ( 40 \times 6028.32 \approx 241133 \text{ cubic inches} ). To convert cubic inches to cubic yards, divide by ( 46,656 ) (the number of cubic inches in a cubic yard), resulting in approximately ( 5.17 ) cubic yards of concrete needed.
