good luck! have a nice day!

C = 62.83 ft.

A = 314.2 ft²

Step-by-step explanation:

circumference of a circle = 2πr

where r = dia./2 = 20/2 = 10 ft.

C = 2 π * 10

C = 62.83 ft.

area of a circle = 2 r²

where r = 10 ft

A = π * 10²

A = 314.2 ft²

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
