The area of the square is 100ft
The average of those five amounts is 183,636.7
AVeraging is adding all of the numbers together with the dividing by a number of numbers you have.
Area = PI x r^2
Circumference = 2 x r x PI
Using area find the radius )r)
616 = 22/7 x r^2
Divide both sides by 22/7:
196 = r^2
Take the square root of both sides:
r = 14 cm
Now find the circumference:
2 x 14 x 22/7 = 88 cm
Answer : A) 88 cm
Another name for ∠2 is ∠PMR.
