Susan designed a circular pool with a diameter of 25 meters. What is the area of the bottom of the pool? Round to the nearest tent.
Please help this is due tomorrow and I need to up my grade.
Area = pi * r^2
A = 3.14 * 12.5^2
A = 3.14 * 156.25
A = 490.6 square meters
a = pi * (25/2)^2
Nothing was said about lawn furniture (or tents).
To find the area of a circle, you can use the formula A = πr², where A is the area and r is the radius of the circle. In this case, the diameter of the circular pool is given as 25 meters.
To find the radius, you can divide the diameter by 2:
r = 25 / 2 = 12.5 meters
Now substitute the value of the radius into the formula to find the area:
A = π × (12.5)²
Calculating this gives us:
A ≈ 3.14 × (12.5)²
A ≈ 3.14 × 156.25
A ≈ 490.875
Rounding this to the nearest tenth gives us the final answer:
A ≈ 490.9
Therefore, the area of the bottom of the pool is approximately 490.9 square meters.
To find the area of the bottom of the circular pool, we can use the formula for the area of a circle. The formula for the area of a circle is:
A = πr^2
where A is the area and r is the radius of the circle.
Given that the diameter of the pool is 25 meters, we can find the radius by dividing the diameter by 2:
r = d/2 = 25/2 = 12.5 meters
Now we can use this value to calculate the area of the bottom of the pool using the formula:
A = π(12.5)^2
Using the value of π as approximately 3.14159, let's do the calculation:
A = 3.14159 * (12.5)^2
A = 3.14159 * 156.25
A ≈ 490.87
Rounding this to the nearest tenth, we get the area of the bottom of the pool as approximately 490.9 square meters.
