The expression representing the volume of the prism is given as:
Volume=[base area]*[height]
base area is the area of the pentagon;
The area of pentagon is given by:
Area of pentagon=a^2ntan(180/n)
a=apothem length
n=number of sides
Area=2.8^2*5tan(180/5)
Area=28.48=28.5 cm^2
Therefore the expression for the volume of the prism with height,h, will be:
volume=28.5h cm^3

Help please, i really need it because its almost due
nata0808 [166]

Answer:

D sqrt( A ) sqrt(pi) / pi = r

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

To find r

Divide each side of the equation by pi

A / pi = pi r^2 /pi

A / pi =  r^2

Take the square root of each side

sqrt(A / pi )= sqrt( r^2)

sqrt(A / pi )= r

We do not like leaving square roots in the denominator, so multiply by sqrt(pi)/sqrt(pi))

sqrt(A / pi ) *sqrt(pi)/sqrt(pi))

sqrt( A ) sqrt(pi) / pi = r
