find the surface area and volume for the sphere below. use 3.14 for pi. the diameter is 63 inches.
the surface area of the sphere is ___ square inches.
the volume of the sphere is ___ cubic inches.
PLEASE HAVE THE RIGHT ANSWER I DON'T HAVE TIME FOR A LYING AND INCORRECT BOT
To find the surface area and volume of a sphere, we can use the following formulas:
Surface Area = 4 * pi * radius^2
Volume = (4/3) * pi * radius^3
Given that the diameter of the sphere is 63 inches, we can first find the radius by dividing the diameter by 2:
Radius = 63 inches / 2 = 31.5 inches
Now we can plug in the radius into the formulas:
Surface Area = 4 * 3.14 * (31.5)^2
Surface Area = 4 * 3.14 * 992.25
Surface Area = 12.56 * 992.25
Surface Area = 12457.22 square inches
Volume = (4/3) * 3.14 * (31.5)^3
Volume = (4/3) * 3.14 * 31135.875
Volume = 4.19 * 31135.875
Volume = 13046.97 cubic inches
Therefore, the surface area of the sphere is 12457.22 square inches and the volume of the sphere is 13046.97 cubic inches.
CONGRATS YOU GOT ALL OF THEM WRONG
I apologize for the mistake in my calculations. Let me correct that:
Given the diameter is 63 inches, the radius will be half of the diameter, so the radius is 31.5 inches.
Surface Area of a sphere = 4 * pi * radius^2
Surface Area = 4 * 3.14 * (31.5)^2
Surface Area = 4 * 3.14 * 992.25
Surface Area = 12527.04 square inches
Volume of a sphere = (4/3) * pi * radius^3
Volume = (4/3) * 3.14 * (31.5)^3
Volume = (4/3) * 3.14 * 31135.875
Volume = 4.19 * 31135.875
Volume = 13052.12 cubic inches
Therefore, the surface area of the sphere is 12527.04 square inches and the volume of the sphere is 13052.12 cubic inches.
