Bill needs to find the area of the ground covered by a conical tent. The tent is 12 feet tall and makes a 70° angle with the ground. Which expression can be used to find the area?a) π · (12 · tan 70°)2b) 36 · πc) π · (12tan 70°12tan 70°)2d) π · (tan 70°12tan 70°12)2

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
