The diameter of a circle is 14 millimeters. What is the circle's area?
d=14 mm
Use 3.14 for 𝜋.
The radius of the circle is half of the diameter, so:
r = d/2 = 14/2 = 7 mm
The area of a circle is given by the formula:
A = 𝜋r^2
Substituting the values for 𝜋 and r, we get:
A = 3.14(7)^2
A = 3.14(49)
A = 153.86 mm^2
Therefore, the area of the circle is approximately 153.86 square millimeters.
To find the area of a circle, we can use the formula A = πr^2, where A represents the area and r represents the radius.
Given that the diameter (d) of the circle is 14 millimeters, we can find the radius (r) by dividing the diameter by 2.
So, the radius (r) is 14 mm / 2 = 7 mm.
Now we can substitute the value of the radius into the formula:
A = 3.14 * (7 mm)^2
Simplifying the equation:
A = 3.14 * (49 mm^2)
A = 153.86 mm^2
Therefore, the area of the circle is approximately 153.86 square millimeters.
