Answer:

True

Step-by-step explanation:

The formula for a cylinder is V = pi*r^2 h

pi*r^2 is the area of the (circular) base.

h = the height.

So the statement for a circular base is true.

This is a very specific case. We ought to try another one.

============

What happens if the base is a regular pentagon?

The area of a pentagon is A=  (1/4) * sqrt(5 + 2*sqrt(5)) * a^2

So that is how to find the base area of a cylinder make up of a regular pentagon.

To find the volume, just multiply by the height.

The answer is True.

Fudgin [204]

Answer:

The total cost is D) $141

Step-by-step explanation:

To solve we can use the equation: y=25d+0.10m

d= number of days  m= number of miles

We know both of these values so we can plug them in and solve.

y= 25(3) + 0.10(660)

y= 75 + 66

y = 141

Snowcat [4.5K]

Based on the stated annual interest rate and the face value of the bond, the semiannual payments will be $1,000,000.

= (50,000,000 x 4%) / 2

= 2,000,000 / 2

= $1,000,000
