Answer:
It could be 2:5 or 6pi:15pi
Step-by-step explanation:
If you write the ratio of the surface area as a fraction, you would get 
. Simplifying it would leave 
. But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is 
. The answers would be 2:5 and 6pi:15pi.
Answer:
38.5 cm^2
Step-by-step explanation:
Area(shaded) = Area(large semicircle) - area(2 small equal semicircles)
= Area (large semicircle) - area (small circle)
= π(7)² x 1/2 - π(7/2)²
22/7 x 7 x 7 x 1/2 - 22/7 x 7/2 x 7/2
= 77 - 38.5
= 38.5 cm^2
