Answer:
63.6m²
Step-by-step explanation:
The radius is 4.5m because it's half of the diameter.
Area = πr²
Area = π(4.5)² = 63.6m²
Alright so it's a rectangle so we know that both lengths are equal to each other and both widths are equal to each other. We know that the area, which is length times width, equals 56 and we also know that the height is 4 yards. So what times 4 equals 56? Calculate 56/4 and you will get 14. The height is 4 yards and the length is 14 yards. You're not done yet though! The question is looking for the perimeter, which is the total of all four sides. Since both lengths and both widths are equal, you would need to do 14+14+4+4. This equals 36 yards. Therefore the perimeter is 36 yards.
