Answer 1

Follows are the solution to this question:

Explanation:

formula for perimeter of semicircle:

`C= \pi * d`

Area of Semicircle:

`A= (\pi r^2)/(2)`

For question 5:

`\to d=17 \ m`

`\to C= \pi * d= 3.14 * 17= 53.38 =53 \\\\`

`\to A= (\pi * r^2)/(2)= (3.14 * 8.5^2)/(2)=(226.865)/(2)=113.4325= 113`

For question 6:

`\to d=10.5 \ in`

`\to C= \pi * d= 3.14 * 10.5= 32.97 =33`

`\to A= (\pi * r^2)/(2)= (3.14 * 5.25^2)/(2)=(86.54625)/(2)=43.273125= 43`
