about 13 ft2

Answer 1

The seconed one , 8 times times I just need to stop . I’m sorry

Answer 2

Area of larger table is about 63 ft² greater.

Explanation:

Given: One circular table has a diameter of 8 ft, and another circular table has a diameter of 12 ft.

To find : How much greater is the area of the larger table.

Solution : We have given

Diameter of a table = 8 ft.

Diameter of another table = 12 ft.

Radius =
`(Diameter)/(2)`.

Radius =
`(8)/(2)`.

Radius of smaller table = 4 ft.

Radius of larger table= 6 ft.

Area of smaller table =
`\pi *( radius)^(2)`

Area of smaller table =
`3.14 *( 4)^(2)`.

Area of smaller table =
`3.14* 16` = 50.24 ft².

Area of larger table =
`\pi *( 6)^(2)`.

Area of larger table =
`3.14* 36` = 113.04 ft².

Area of larger table - area of smaller table

= 113.04 - 50.24 .

= 62.8 ft².

= about 63 ft².

Therefore, Area of larger table is about 63 ft² greater.
