To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²
Answer:
Subtract
from both sides.
Step-by-step explanation:
We want to isolate the variable
. To do this, we have to get rid of
, which we can do by subtracting itself, since it equals 0.
