A company makes globes with a radius of 11 inches. The material to make the globes costs the company $0.04 per square inch. To the nearest cent, how much does the company pay for the material to create one globe? Use 3.14 for pi. Recall the formula SA=4 pi r^2.$11.05$60.79$243.16$607.90
Accepted Solution
A:
Answer:One globe costs $60.79Step-by-step explanation:The area of the globe is A = 4.π.r^2Since the radius is 11 inchesA = 4*(3.14)*(11 in)^2 = 1519.76 in^2We apply a rule of three1 in^2 --------------------------------- $0.041519.76 in^2 ------------------------- xx = (1519.76 in^2/ 1 in^2)*$0.04x = (1519.76)*$0.04x = $60.79x ≈ $60.8
