So to do this one, you have to do the problem backwards!
The equation looks like this with everything plugged in:
272.2 = 2(3.14)r
You are looking for r, so start dividing
272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r
Therefore the radius is about 43.3 in.
I hope I helped!
Answer:
I'm pretty sure it is 18
Step-by-step explanation:
Since the shape is not a perfect square you can count how many blocks are shaded. However, the half shaded blocks, since they are half shaded you will need 2 half shaded blocks to make one block
5 cm since a pentagon has 5 sides just multiply one side by 5
1x5=5
2.25 as a fraction is 2 1/4
