Answer :
Answer: 1134.1 mm^2
Step-by-step explanation:
To find the area of a circle, you can use the formula:
A = pi r^2
Given:
- Radius (r) = 19 mm
Substitute the value of the radius into the formula:
A = pi(19mm)^2
Calculate the square of the radius:
19^2 = 361
Now, substitute 361 into the formula:
A = pi x 361mm^2
Using the approximate value of (pi =3.14159):
A = 3.14159 x 361
Multiply to find the area:
A = 1134.11459mm^2
Rounding to one decimal place:
A = approx 1134.1 mm^2
Thus, the area of the circle is approximately 1134.1 mm^2.
