Answer:
b) 24 rows
Step-by-step explanation:
12 inches = 1 foot
Since we are doing 30 feet, multiply 12 by 30
12 · 30 = 360 inches
Then, divide the total length (360 inches) by the spacing size (15 inches)
360 ÷ 15 = 24 rows total
I think that C and D are the correct answers
Answer:
4/5 of 3 = 12/5
2/9 of 20 = 40/9
Step-by-step explanation:
Don't study your heart out, but study here and there and don't stress.
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.
