Answer:
48, 11, and 90 from top to bottom
Step-by-step explanation:
Hi! You again!
so for every adult, there are 6 children
8+8+8+8+8, or 8x6, is 48
15+15+15+15+15+15, or 15x6 is 90
and the middle is where it's a bit tricky, since we have to divide instead of multiply.
we're trying to find out what times 6 is 66.
11+11+11+11+11+11 is 66.
Area of a semi-circle = 1/2 x x r square.
area of larger semi circle
= 1/2 x x 10 square
= 50
area of smaller semi circle
= 1/2 x x 5 square
= 12.5
Total area = 50 + 12.5 = 196 cm square ( to 3 sf ) or 62.5
