Find the area of a circle with a diameter of 8 cm
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is twice the radius, the radius of the circle with a diameter of 8 cm is 4 cm.
Substitute the value of the radius into the formula:
A = π(4 cm)^2
A = π(16 cm^2)
A = 16π cm^2
The area of the circle is 16π square centimeters.
That's not right
Apologies for the error. Let's correct that:
Given that the diameter of the circle is 8 cm, the radius (r) would be half of the diameter:
r = 8 cm / 2 = 4 cm
Now, we can use the formula for the area of a circle, which is A = πr^2:
A = π(4 cm)^2
A = π(16 cm^2)
A = 16π cm^2
The area of the circle with a diameter of 8 cm is 16π square centimeters.
Still not correct
I apologize for the mistake in my previous responses. Let's correct it:
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. In this case, the diameter of the circle is 8 cm, so the radius is half of the diameter, which is:
r = 8 cm / 2 = 4 cm
Now, we can calculate the area using the formula:
A = π(4 cm)^2
A = π(16 cm^2)
A = 16π cm^2
Therefore, the area of a circle with a diameter of 8 cm is 16π square centimeters.
