Answer:
89.95 inches.
Step-by-step explanation:
We are asked to find the best approximation for the perimeter of a semicircle whose diameter is 35 inches.
, where D represents diameter of semicircle.
Upon substituting D=35 and
in above formula we will get,
![\text{Perimeter of semicircle}=\frac{1}{2}\times 3.14\times 35+35](https://tex.z-dn.net/?f=%5Ctext%7BPerimeter%20of%20semicircle%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%203.14%5Ctimes%2035%2B35)
![\text{Perimeter of semicircle}=3.14\times 17.5+35](https://tex.z-dn.net/?f=%5Ctext%7BPerimeter%20of%20semicircle%7D%3D3.14%5Ctimes%2017.5%2B35)
![\text{Perimeter of semicircle}=54.95+35](https://tex.z-dn.net/?f=%5Ctext%7BPerimeter%20of%20semicircle%7D%3D54.95%2B35)
![\text{Perimeter of semicircle}=89.95](https://tex.z-dn.net/?f=%5Ctext%7BPerimeter%20of%20semicircle%7D%3D89.95)
Therefore, perimeter of our given semicircle is 89.95 inches.

Answer:
Step-by-step explanation:
Step-by-step explanation:
p^2+b^2=h^2
or, 16+9=h^2
or, 25=h^2
or h=5
again, p^2 +b^2=h^2
or, 25+b^2=36
or, b^2=11
or. b=√11 therefore b=x=√11
