The diagram below shows the radius of the face of a watch 11 mm which of the following is the closest to the area of the face of the white a34.54 mm b 34.33 mm c 1,519.76 mm d379.94 mm
To find the area of the face of the watch, we need to calculate the area of a circle with radius 11 mm.
The formula to calculate the area of a circle is:
Area = πr^2
Given that the radius is 11 mm, we can plug this into the formula:
Area = π(11)^2
Area = π(121)
Area = 121π
Using an approximation of π as 3.14, we can calculate:
Area ≈ 121 * 3.14
Area ≈ 379.94 mm
Therefore, the closest option to the area of the face of the watch is d) 379.94 mm.
You sure
I made an error in my calculation. Let's correct it.
The area of a circle with a radius of 11 mm is calculated as follows:
Area = π * (11)^2
Area = 121 * π
Area ≈ 121 * 3.14
Area ≈ 380.94 mm^2
Therefore, the closest option to the area of the face of the watch is actually d) 379.94 mm.
