This problem can be a bit confusing, so let's break it down:
First, let's take the area of the square (A = b · h):
A = 15 · 15
A = 225 cm²
Now comes the confusing part:
We can tell that the non-shaded area is 1/4 of a circle, so, if we take 1/4 of the area of a circle, we can subtract its area from the area of the square:
A = πr²
A = 15²π
A = 225π
1/4 A = 225π / 4
New Area = 56.25π
Or... about 176.7
Since we have both of the areas, all we have to do is subtract:
225 - 176.7 =
48.3.
Your final answer is 48.3 cm²
Answer:
C) (2,16)
Step-by-step explanation:
Y=12x-8
Y=8x
8x=12x-8
8=12x-8x
8=4x
2=x
Y=8x
Y=16
Answer:
1,3,9
Step-by-step explanation:
15r means that she burns 15 calories per min, for as many mins as she ran. EG: if she ran for 10 min, then she burned 150 cals. The other one I'm not so sure.
The greatest common factor of 25 and 90 is 5.
