Please answer this correctly

Answer 1

593
`mm^(2)`

Explanation:

3.14 ×
`17^(2)` = 907.46

3.14 ×
`10^(2)` = 314

907.46 - 314 = 593.46

Answer 2

Answer: 593.46 mm²

Explanation:

The diameter of the big circle is 2(7) + 20 = 34

divide the diameter by 2 to get the radius (r) = 17

Area = π·r²

= π(17)²

= 289 π

The diameter of the big circle is 20

divide the diameter by 2 to get the radius (r) = 10

Area = π·r²

= π(10)²

= 100 π

The area of the shaded region is the difference between the area of the big circle and the area of the small circle.

`Area_(shaded)=Area_(big)-Area_(small)`

= 289 π - 100 π

= 189 π

= 189(3.14)

= 593.46
