1. What is the approximate area of a circle with a diameter of 20 inches? 2. What is the volume of a cube with a side length of 3 cm?

3. What is the median of the data set { 35,20, 30,25,20 }?

1. 100

2. 27

3. 30

Step-by-step explanation:

Area =

       = x

       = 100

Volume = l x w x h

             = 3 x 3 x 3

             = 27

step-by-step explanation:

first, eliminate the parenthesis:

3

x

+

2

−

4

x

second, group like terms:

3

x

−

4

x

+

2

third, combine like terms:

(

3

4

)

x

the two may have that, even a breakdown is probably offered
