Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
Answer:
Step-by-step explanation:
X = 1/2 arc QS
arc QS is
360 =145+105+QS
110 = QS
so X is 1/2 QS

Answer:
x = 4.
Step-by-step explanation:
2x + 3(5x - 7) = 47
2x + 15x - 21 = 47
17x - 21 = 47
17x = 68
x = 68/17
x = 4.
