#3)  The ends create a circle whose radius is 0.4 m   --->   Area  =  pi·(0.4)2

The rectangle   --->   Area  =  2 · 0.8

To find the volume, multiply that answer times 2.8.

Multiply the volume by 1000 to get the capacity in meters.

To find the cost:

--  you have the area of the bottom, so multiply that value times \$40.00

--  to find the area of the sides, find the circumference of the tank and multiply that number

by the height:  there are two sides of 2 m each and now we need the circumference of

the circle:  C  =  pi·diameter  =  pi·0.8  =  2.513

The total circumference of the tank is 2 + 2 + 2.513  =  6.513.

To get the area:  6.513 x 2.8  =  18.24

Multiply this by \$40.00 and add to the value above.
