The cost to rent a car is $25 plus an additional $0.15 for each mile the car is driven. Which of the following equations could b
e used to find the number of miles, m , a car was driven if the car had a bill of $71.80? 71.8 m + 25 = 0.15
25 m + 0.15 = 71.8
25 + 0.15 m = 71.8
0.15 m + 71.8 = 25
We know that [surface area of a sphere]=4*pi*r² r²=surface area/(4*pi) r=√[surface area/(4*pi)] surface area=450 in² r=√[450/(4*pi)]------> r=5.98 in------------> r=6 in
