Answer:
2.1
Step-by-step explanation:
The formula for a cone is pi * r^2 * (h/3) or pi* r^2 * h * 1/3.
Since the height is 7ft and the radius if 4ft you plug those into the equation and get:
V= 1/3 * pi * (4^2) * (7)ft cubed which is the answer of B
Answer:
B);2.48×10^12
Step-by-step explanation:
so there it is
Answer:
Step-by-step explanation:
This is a perfect square.
So the final expression is
Collect like terms so that the equation becomes 14x-44=180
Move negative 44 to the other side as a positive so equation becomes
14x=224
Divide both sides by 14
224/14 which is 16
So x is equal to sixteen
