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.
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.

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.

That’s still not right
