The diagram below shows the radius of the face of a watch.
watch is 11mm
Which of the following is closest to the area of the face of the watch?
Responses
A 34.54 mm²
B 34.33 mm²
C 1,519.76 mm²
D 379.94 mm²
The radius of the face of the watch is half of 11mm, so it is 5.5mm.
The area of a circle is given by the formula A = πr^2, where r is the radius.
Substitute r = 5.5mm into the formula:
A = π(5.5)^2
A = π(30.25)
A ≈ 94.98 mm²
The closest answer choice to this calculated area is D) 379.94 mm².
