Answer:
The correct answer is:
r + 0.50 = 10.25: Subtract .50 from both sides. The answer is $9.75.
This is because Juan got a $0.50 raise which means that his new rate will be $0.50 more than his original rate (r).

Answer:1
V = 62.1262 cubic inches
Step-by-step explanation:
The formula for volume of a cone is V = (1/3)πr²h where r is the radius of the base, and h is the height.
We are given the height, h = 7 1/2 inches, or 15/2 inches
We are given the diameter of the base of 5 5/8 inches, or 45/8 inches
The radius is half the diameter, so divide 45/8 by 2. The radius is 45/16.
Plug these values into the formula and find V
V = (1/3)π(45/16)²(15/2)
V = 30,375π/1,536 = 62.12622191
rounding to 4 decimal places gives us 62.1262 cubic inches
