You can look up cone caculators for these questions. Also wierd question if you have an old 5 paragraph essay i can have i posted a question for 1 for 50 points on my account ( doesnt matter the topic)
Start with an equation that relates base diameter (d), height (h), and volume (V): V=(1/12)(pi^2)(d^2)h
Then, substitute known values into the equation: V=(1/12)(7^2)(8pi)
Finally, solve the equation: V=((7^2)(8pi))/12 V=(2(7^2)pi)/3 (the GCD of 12 and 8 is 4, so we can simplify by dividing by 4/4) V=(2(49)pi)/3 V=98pi/3 (or approx. 102.625)
