Question

The total force on a boiler safety valve is determined by the area of the valve disk. What is the area of a safety valve disk with a radius of 1.75 in.? (Area of a circle)

Answer 1

The area of the safety valve disk with a radius of 1.75 in. is approximately 9.62 square inches.

Step-by-step explanation:

The area of a safety valve disk can be calculated using the formula for the area of a circle, which is A = πr^2. Given that the radius of the valve disk is 1.75 in., we can substitute this value into the formula to find the area:

A = π(1.75)^2 = 9.62 in^2

Therefore, the area of the safety valve disk is approximately 9.62 square inches.
