D might be the answer I am pretty sure it is D if not then sorry
Answer:
a. 21
Step-by-step explanation:
The formula for volume of a cone is V=(1/3)*h*π*(r^2)
our height is 7.5 feet, and since the length of the base of the cone (diameter) is 22 feet long, the radius is 11 feet long.
(1/3)*7.5*π*(11^2)=302.5*π=950.3
so the volume of the house is about 950 feet cubed.
When dividing fractions you keep the first fraction, change the division sign to multiplication, and flip the second fraction. (Keep Change Flip) For mixed numbers, make it a fraction by multiplying the whole number times the denominator, adding that to the numerator, and put that sum over the same denominator. Then do Keep Change Flip
Answer=C
Let's first solve for the volume of the cube
V=s³
V=9³
V=729cm³
1 liter is 1000cm³
1L=1000cm³
1L x L
_______ = _______
1000cm³ 729cm³
Cross multiply
1000x=729
divide both sides by 1000
x=0.729L
Answer=0.729L
