Answer:
864ft^3
Step-by-step explanation:
Divide the diameter by 2 to get the radius
12 / 2 = 6
Then solve the volume equation using 3 for pi.
4/3 * 3 * 6^3
4 * 6^3
4 * 216 = 864
Given:
perfect score- 100
number of questions of the test- 25
worth of each question- 4 points
Fred's score- 84
n- number of questions Fred had answered incorrectly.
solution:
solve for n
division sentence: (100 ÷ 4 ) - ( 84 ÷ 4 ) = n
(100 ÷ 4 ) - ( 84 ÷ 4 ) = n
25 - 21 = n
4= n
therefore, Fred had answered 4 test questions incorrectly.

The simple interest that is paid on an amount of money is a function of the amount deposited, time and interest rate.
Simple interest = principal x time x interest rate
2666 = 4300 x 0.062 x t
2666 = 266.60t
t = 2666 / 266.60
t = 10 years
