Find the area for the circle use 3.14 for pi. round to the nearest tenth
4mm is in the middle
A. 12.56 mm squared
B. 25.12 mm squared
C. 50.24 mm squared
D. 502.4 mm squared
I assume the diameter is 4 mm
A = pi * r^2
A = 3.14 * 4
A = ______ mm^2
To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle. In this case, the radius of the circle is 4 mm.
Step 1: Square the radius
4 mm * 4 mm = 16 mm^2
Step 2: Multiply by π (approximately 3.14)
16 mm^2 * 3.14 = 50.24 mm^2
The area of the circle is 50.24 mm^2.
Rounded to the nearest tenth, the answer is:
C. 50.2 mm squared
To find the area of a circle, we can use the formula A = πr^2, where A is the area and r is the radius of the circle.
In this case, we know that the radius of the circle is 4 mm. So, substituting the given value into the formula, we get:
A = 3.14 × (4)^2
A = 3.14 × 16
A = 50.24 mm squared
Therefore, the area of the circle is 50.24 mm squared.
Rounded to the nearest tenth, the answer is C. 50.24 mm squared.
