Question

Evaluate r2h for = 3.14, r = 1 and h = 2. Round your answer to the nearest whole number and type a numerical answer in the space provided.

Answer 1

The answer in the procedure

Explanation:

we have

`\pi=3.14`

`r=1\ units`

`h=2\ units`

case a) If the expression is

`\pi r^(2) h`

then

substitute

`(3.14)(1)^(2) (2)=6.28\ units^(3)`

Round to the nearest whole number

`6.28=6\ units^(3)`

case b) If the expression is

`(1/3)\pi r^(2) h`

then

substitute

`(1/3)(3.14)(1)^(2) (2)=2.09\ units^(3)`

Round to the nearest whole number

`2.09=2\ units^(3)`
