The diameter of a circle is 8 inches. What is the circle's area?
d=8 in
Use 3.14 for 𝜋.
The radius of the circle is half of the diameter, so it is 4 inches.
The formula for the area of a circle is A = 𝜋r^2.
Substituting in the values, we get:
A = 3.14 x 4^2
A = 3.14 x 16
A = 50.24
Therefore, the area of the circle is 50.24 square inches.
To find the area of a circle, you can use the formula:
A = 𝜋 * r^2
Given that the diameter is 8 inches, we can find the radius by dividing the diameter by 2:
r = d/2 = 8/2 = 4 inches
Now we can substitute the radius in the formula:
A = 3.14 * 4^2 = 3.14 * 16 = 50.24 square inches
Therefore, the area of the circle is 50.24 square inches.
