Question

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 }?

Answer 1

1. 100
`\pi`

2. 27
`cm^(3)`

3. 30

Explanation:

Area =
`\pi`
`r^(2)`

=
`\pi` x
`10x^(2)`

= 100
`\pi`

Volume = l x w x h

= 3 x 3 x 3

= 27
