Find the volume of each prism round to the nearest tenth if necessary

V=1 /4*h*sqrt(﹣a^4+2(ab)^2+2(ac)^2﹣b^4+2(bc)^2﹣c^4)

h = sqrt(3^2 + 5^2) = 5.80

 43.63 units^3

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

if x = 1, then the answer is 3.5
