Answer:
c
Step-by-step explanation:
This shape is made from a four sided shape which is 360°
and a three sided shape which is 180°
so the combined interior degrees is 540°
so
3x + 6x+ 1 + 2x + 4x + 5x-1 = 540
20x = 540 combine like terms
/20 /20
x = 27
3+7=10 because three and seven are both in your equation so after adding 3 and 7 all you must do is add 5 to 10
Answer:
the pile has a height H = 15.09 ft
Step-by-step explanation:
The volume of a cone V is
V= 1/3*π*H*R²
where H= height , R=radius
if the diameter D=2*R is 3 times its height
D=3*H → 2*R=3*H → R=3/2*H
then
V= 1/3*π*H*R² = 1/3*π*H*(3/2*H)² = 1/3*π*H*9/4*H² = 1/12*π*H³
V= 1/12*π*H³
if the volume is V=900 ft³ , then solving for H
V= 1/12*π*H³
H = ∛(12*V/π) = ∛(12*900 ft³/π) = 15.09 ft
H = 15.09 ft
then the pile has a height H = 15.09 ft
