Answer:
Area of regular pentagon is 238.95 square inches.
Step-by-step explanation:
Given a regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches.
we know a regular polygon divides into 5 congruent triangles.
Side of pentagon i.e base of one triangle is 11.8 inches.
Also, distance from center to middle of side which is height of triangle is 8.1 inches.
Area of 1 triangle=
=
= 47.79 sq inches.
Area of regular pentagon=area of 5 congruent triangles= =238.95 sq inches.

Answer:
So the radius is increasing at .
This is approximately 0.00497 cm/min that the radius is increasing.
Step-by-step explanation:
The volume and radius are both things that are changing with respect to time.
So their derivatives will definitely not be 0.
Let's differentiate:
I had to use constant multiple rule and chain rule.
We are given and .
We want to find .
Let's plug in first:
Multiply both sides by 3:
Divide both sides by :
So the radius is increasing at .
This is approximately 0.00497 cm/min that the radius is increasing.
