Volume of a cone: 1/3
r²h
r is the radius (diameter ÷ 2) and h is the height.
Find the radius first using the diameter: 2
÷ 2 = 1.25
Now plug in the numbers into the formula.
1/3
1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.

Hi,
The greatest common factor of 30 and 50 is 10.
Have a great day!
Yes and no. A negative number and it's opposite are 'integers.' Yes, a negative and a negative multiplied together give you a positive. The two negative signs cancel out making it positive. But no, a positive and a positive multiplied together do not give you a negative. When you subtract positive numbers you can get a negative, but not when multiplying. If you were to do a positive times a negative it would be negative because the positive can't cancel it out. Example: -3 · -3 = 9. [] 3 · 3 = 9. [] -3 · 3 = -9. Other than the positive number part, the statement is true about the negatives. I hope that helped!
