Answer:
24.997 cm
Step-by-step explanation:
C=2πr
C=2 x 3.142 x 7 = 43.988
43.988/4 = 10.997
10.997 + 7 + 7 = 24.997
PN = PM
6x + 1 = 10x - 17
Add both sides 17
6x + 1 + 17 = 10x - 17 + 17
6x + 18 = 10x
Subtract both sides 6x
6x - 6x + 18 = 10x - 6x
18 = 4x
Divide both sides by 4
18 ÷ 4 = 4x ÷ 4
9/2 = x
x = 9/2
___________________________
QN = 2x + 5
QN = 2 × ( 9/2 ) + 5
QN = 9 + 5
QN = 14
You could use the formula they give you when you solve for c you square those numbers then add them find the square root of the product of those numbers added together that should be your answer
