Answer:
Follows are the solution to this question:
Step-by-step explanation:
formula for perimeter of semicircle:
[tex]C= \pi \times d[/tex]
Area of Semicircle:
[tex]A= \frac{\pi r^2}{2}[/tex]
For question 5:
[tex]\to d=17 \ m[/tex]
[tex]\to C= \pi \times d= 3.14 \times 17= 53.38 =53 \\\\[/tex]
[tex]\to A= \frac{\pi \times r^2}{2}= \frac{3.14 \times 8.5^2}{2}=\frac{226.865}{2}=113.4325= 113[/tex]
For question 6:
[tex]\to d=10.5 \ in[/tex]
[tex]\to C= \pi \times d= 3.14 \times 10.5= 32.97 =33[/tex]
[tex]\to A= \frac{\pi \times r^2}{2}= \frac{3.14 \times 5.25^2}{2}=\frac{86.54625}{2}=43.273125= 43[/tex]
