Answer: a semicircle is half the perimeter (or circumference) of its full circle, so the full circle here has a circumference of 20.56
Use that to figure out the length of the radius: Circumference divided by 2(pi) will give you the radius.
Once you have the radius, use the formula for Area of a Circle: A = pi * radius2.
Once you have the area of the circle, divide that by 2 to get the area of the semicircle.
π=3.14 C=3.14 x 8cm C=25.1cm Divide by 2 for the semicircle 12.5 Add the diameter (8cm) 12.55+8=20.5
Answer:
Ankita is 135cm tall and Nita is 150cm tall- to find what percent of Nita's height Ankita represents you would divide ankita's height by Nita's height then multiply the answer by 100%
135cm/150cm = 0.9 (the centimetres cancel out and leaves a generic unit) then 0.9 x 100% = 90%
so Ankita is 90% of the height of Nita
