Answer:
13.76 square meters
Step-by-step explanation:
The side of square is 8 meters.
So, the diameter of circle = 8 meters.
⇒ Radius = (diameter of circle) ÷ 2 = 8 ÷ 2 = 4 meters
Shaded region = Area of square - Area of circle
= (Side × Side) - π × (radius)²
= 8 × 8 - π × 4 × 4 {∵ π = 3.14 or 22÷7}
= 64 - 50.24
= 13.76 square meter
The first part of the answer can be found by finding the GCF between 15 and 25. 15 is divisible by 1, 3, 5, and 15. 25 is divisible by 1, 5, and 25. You can see that their GCF is 5. Next, you need to look at the variables. The first monomial has a, b, and 
. The second monomial has 
, b, and c. They each have at least one a, one b, and one c, so those will be in the GCF (abc). If you put that together with the 5, you get that the GCF is 5abc.
