Answer 1

Area of the circle = 616
`cm^(2)`

Volume of the rectangular prism = 416
`mm^(3)`

Explanation:

Area of a circle =
`(22)/(7)r^(2)` where, r is the radius.

To find the radius, take the half of diameter

`(28)/(2) =` 14

=
`(22)/(7)`
`14^(2)`

=
`(22)/(7)` × 196

= 22 × 28

= 616
`cm^(2)`

Volume of a rectangular prism = length × breadth × height

= 10.4 × 5 × 8

= 416
`mm^(3)`
