The figure is made up of a cone and a cylinder.

Diameter = 16 ft
radius = 16÷2 = 8ft

Volume of the cone = 1/3bh
Volume of the cone = $\frac{1}{3} \pi r^{2} h$
Volume of the cone = $\frac{1}{3} \pi 8^{2}(6)$ = 402.12

Volume of the cyclinder = bh
Volume of the cylinder = $\ \pi r^{2} h$
Volume of the cylinder = $\ \pi 8^{2}(4)$ = 1206.37

Total = 402.12 + 1206.37 = 1608.49 cubic feet

when you subtract a negative integer from another, will your answer be greater than or less than the integer you started with? e

BlackZzzverrR [31]

It depends if the negative number is bigger than the positive number your answer will be a negative number/answer for example -9 - 4 your answer would be -5 since the negative number is bigger it will be the other way around for a positive number if the positive number is bigger than the negative number your answer will be positive for example 5 - -2 = 3 or positive 3.
