2 to the 8th power is 256.
It's the same as doing 2x2x2x2x2x2x2x2=256.
"<span>A= 1/2 h (a+b) solve for h"

bh + 1/2h
160 is 100% of 160, 480 is 4 times that. So 400%
Diameter of the dartboard as given in the question = 18 inches
Then
Radius of the dartboard will be = 18/2 inches
= 9 inches
We already know that
Circumference of a circle = <span>2π</span>r
We also know that the value of <span>π = 3.14159
Then
Circumference of the dartboard = 2 * 3.14159 * 9 inches
= 56.548 inches
= 56.55 inches
So the radius of the dartboard is 9 inches and the circumference of the dartboard is 56.55 inches. I hope the procedure is absolutely clear to you.
