Question

Find the area of the following figures.

Answer 1

find the radius of the semi circle 1st

\[24.5 \pi = \frac{1}{2} \pi r^2\]

solve for r

\[49\pi = \pi r^2\]

\[49 = r^2\]

r = 7

then the base of the triangle is 14 cm...( a diameter)

Area of the triangle = 1/2 x 14 x 18

total area = triangle + semi circle

Answer 2

Please come back, how did you get 18?

Answer 3

height=15
as it is total height -radius of semicircle
i.e.
22-7 =15

Answer 4

They meant 22-7=15 for the height

Answer 5

I see! thank you so much

Answer 6

so is the total area 105 + 24.5pi?

Answer 7

yes ryt...

Answer 8

Thank you :)
