If I had to find the area of a circle
(3.14)r^(2)
- and it states that it is 5 meters in diameter
would I divide 5 by 2 = 2.5 and then multiply 2.5 by 2.5 to get 6.25?
Yes.
Then: 3.14 * 6.25 = A
Thank you
Youre welcome.
To find the area of a circle, you need to use the formula A = πr^2, where A represents the area and r represents the radius of the circle. In this case, you mentioned that the diameter of the circle is 5 meters.
To find the radius, you divide the diameter by 2. So, if the diameter is 5 meters, you would perform the calculation 5 / 2 = 2.5 meters.
Once you have the radius, you can find the area by substituting it into the formula. Plug in the value of the radius (2.5 meters) into the formula.
A = π(2.5)^2
Simplifying further,
A = 3.14 * 2.5^2
Now, calculate the square of the radius:
A = 3.14 * 6.25
Finally, multiply π (approximately 3.14) by 6.25 to get the area.
A ≈ 19.625 square meters
So, the area of the circle with a diameter of 5 meters is approximately 19.625 square meters.
