Answer:
37.7 inches
Step-by-step explanation:
V=πr^2h
Is the formula for the volume of a cylinder
^2 is exponent 2
r is the radius (2) and h is the height (3)
It would be 3h(3h^2 -4), it is factored
X= -1
2x+4-x=x+3-x subtract x from both sides
x+4=3
x+4-4=3-4 subtract 4 from both sides
Therefore, x=-1
Answer:
A= 120ft^2
Step-by-step explanation:
In the smaller triangle the base is 10. The larger is twice as much as that base. So the height must be twice as much as the smaller (6 x 2 = 12)
b=20
h=12
SO..
A= bh/2
20(12)/2
240/2
A=120
Hope this helped!!!
