An object is made of a prism with a spherical cap on its square shaped top. The cap's base has a diameter equal to the lengths of the top. The prism's height is 7 , the cap's height is 8 , and the cap's radius is 8 . What is the object's volume?

color(maroon)("Volume of the object " = pi r^2 H + (2/3) pi r^3 ~~ 2479.7638 " cubic units"

Explanation:

"Volume of the object " = " Volume of cylindrical prism + Volume of spherical cap (or hemisphere)"

"Vol. of Spherical Cap " V_s = (2/3) pi r^3 " as " r = h

"Volume of Prism = V_p = pi r^2 H

"Given ' r = 8, H = 7

"Vol. of object " V_o = V_p + V_s

V_o = pi ^ 8^2 * 7 + (2/3) * pi * 8^3

color(maroon)(V_o = pi * 8^2 * ( 7 + 16/3) ~~ 2479.7638 " cubic units"
