Multiple Choice Question (MCQ)
Question: What is the minor diameter of Trapezoidal square thread Tr 40 x 7 depth clearance of 0.01 mm?
A.
32.98 mm
B.
33.00 mm
C.
36.49 mm
D.
36.50 mm
Correct Answer: 32.98 mm
Explanation
The area of a sector of a circle can be calculated using the following formula:
Area of sector = (Angle of sector / 360) x (pi x (radius)^2)
where the angle of the sector is measured in degrees and the radius is measured in the same units (e.g. cm).
Given the radius of 5 cm and an angle of 96 degrees, we can substitute the values into the formula and calculate the area:
Area of sector = (96 / 360) x (pi x (5)^2) Area of sector = (0.2667) x (pi x 25) Area of sector = (0.2667) x 78.5398 Area of sector = 21.0014 sq cm
So the area of a sector of a circle with radius of 5 cm and an angle of 96 degrees is approximately 21.0014 square centimeters.
