Step-by-step explanation:
A^2+b^2=c^2 so 8^2+b^2=9^2 so 64+b^2=81 so b^2=17 so b=4.12
Answer:
you get 6.90372 so i thnk it is clse to B
Answer:
The answer is C=942.48
Step-by-step explanation:
You would figure this out by using the formula C=2πr.
So let's break this down.
Circumference (C) equals (=) pi (π) times 2 times the radius of the circle.
Since the problem gave you the diameter which is the length from one side of the circle to the other, you have to divide the diameter in half. Which would give you a radius of 150.
Taking the 150 you would multiply 10*2*π.
Which would give you....(drumrollllll)
C=942.48
I hope this helps!!
