find the surface area and volume for the sphere below. use 3.14 for pi. the diameter is42 inches.
the surface area of the sphere is ___ square inches.
the volume of the sphere is ___ cubic inches.
PLEASE HAVE THE RIGHT ANSWER I DONT HAVE TIME FOR A LYING AND INCORRECT BOT
To find the surface area and volume of a sphere, we use the formulas:
Surface Area = 4πr^2
Volume = (4/3)πr^3
Given that the diameter is 42 inches, the radius (r) is half of the diameter, so r = 21 inches.
Surface Area = 4 * 3.14 * 21^2
Surface Area = 4 * 3.14 * 441
Surface Area = 1756.56 square inches
Volume = (4/3) * 3.14 * 21^3
Volume = (4/3) * 3.14 * 9261
Volume = 4.18667 * 9261
Volume = 38804.25 cubic inches
Therefore, the surface area of the sphere is 1756.56 square inches and the volume is 38804.25 cubic inches.
