There is a problem here. A circle with a 7-foot diameter has a circumference of 21.99 feet, not 10 feet.
If the circumference is 10 feet, that would make the diameter 3.183 feet.
Circumference = 10*pi = 31.416 feet rounded to three decimal places
i would say 10ft, which part is actually 10 ft
Circumference = 62.8 ft so angle is 20/62.8 x 360 ie 114.6o
We don't know how 'xy' is related to the circle. We really have to see the picture. On the off-chance that 'xy' may be a diameter of the circle, the area is 78.54 square feet. But that's just a wild guess, and a shot in the dark.
First you times 3.14 by the diameter and there you go
It is: diameter = 31.4/pi which is about 10 units
Circumference = 10*pi = 31.416 feet rounded to three decimal places
Your question is incomplete. What is the question? Total diameter, outer circumference, what?

Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
First you times 3.14 by the diameter and there you go
Volume = pi*52*10 = 785.398 cubic feet to 3 decimal places
12,345 gallons
A= pi r squared 3.14 * 10 *10 = 314 square feet.
A round pool with a 10-foot diameter and a 3-foot depth can hold up to 1,762 gallons of water.
