Tip: the watch’s diameter is 11mm
Which of the following is closest to the area of the face of the watch?
Responses
A 34.54 mm²34.54 mm²
B 34.33 mm²34.33 mm²
C 1,519.76 mm²1,519.76 mm²
D 379.94 mm²
To find the area of the watch's face, you need to use the formula for the area of a circle: A = πr^2, where r is the radius of the circle.
Given that the diameter of the watch is 11mm, the radius would be half of the diameter, which is 5.5mm.
Now, substitute the radius into the formula: A = π * 5.5^2 = 95.03 mm²
Among the given options, the closest area to 95.03 mm² is:
B 34.33 mm²
