Answer:
Diameter: 14
Radius: 7
Step-by-step explanation:
To find the diameter, you do 43.96 divided by 3.14 and that equals 14
To find the radius, you just divide 14 by 2 and that equals 7.
Answer:
16

Answer:
45 km^2 (C)
Step-by-step explanation:
Isolate the smaller square -
We only need two side lengths, take 3km and 3km.
3×3 = 9km^2, that's the area of the smaller square.
Isolate the larger square -
Take 6km and the other 6km
6×6 = 36km^2
Add the square's areas together to get the whole area -
36 + 9 = 45km^2
All you need to do to solve these problems is to isolate the shapes and find their area's, and finally add them together.
