What is the cross sectional area of a golf ball?
The area of a circle is pi x r2 So you just have to find the radius of your circle, which is the radius of your golf ball. Then substitute it into the area of a circle formula as above.
What is the cross sectional area of the 4 pipe?
Method to find area of a circle is: The area of a circle is its radius squared times pi. Assuming the pipe has a diameter of 4cm: radius = 2 cm Circumference = 12.5664 cm Area = 12.5664 cm2
What is the cross sectional area of the 4 inch pipe?
The cross-sectional area of a pipe can be calculated using the formula for the area of a circle, A = πr^2, where r is the radius of the pipe. Since the diameter of the pipe is given as 4 inches, the radius would be half of the diameter, so r = 2 inches. Plugging this value into the formula, we get A = π(2)^2 = 4π square inches. Therefore, the cross-sectional area of the 4-inch pipe is 4π square inches.
How much water does a 100 foot hose with 1.5 inch diameter hold?
To calculate the volume of water held by the hose, we first need to find the cross-sectional area of the hose. The formula for the area of a circle is A = πr^2, where r is the radius of the hose (which is half the diameter). In this case, the radius is 0.75 inches. Converting the radius to feet (0.0625 feet), we can calculate the area of the hose's cross-section. Multiplying the cross-sectional area by the length of the hose (100 feet) gives us the volume of water held by the hose.
How do you find the volume of a trapezium?
