Ruby red paint costs $0.50 per square inch. a ball is painted ruby red and costs $100.00 to paint. what is the diameter of the ball? round to the nearest tenth of an inch.

Assumes:  ball is equivalent to spherical shape

Find surface area (painted):
($100.00)/($0.50 / in²) = 200 in²

Surface area of sphere:
SA = 4πr²

(200 in²) = 4πr²

r² = (200 in²)/(4π) = 15.91549431 in²

r = √(15.91549431) = 3.989422804 in

diameter = 2r = 2(3.989422804 in) = 7.978845608 in

Rounded to the nearest tenth of an inch:

d = 8.0 inches

 . . .  answer is . . . diameter = 8.0 inches

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
