    Find the distance around a circle with a diameter of 9 ft. 

    Explanation
    The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is given as 9 ft. Plugging this value into the formula, we get C = π(9) = 28.26 ft. Therefore, the correct answer is 28.26ft, 28.26, 28.26 feet, 28.26feet, 28.26 ft.

    The can of paint shown below has a radius of 5.5 inches. What is the length of the label that goes around the outside of the can.  - ProProfs

    The can of paint shown below has a radius of 5.5 inches. What is the length of the label that goes around the outside of the can. 

    Explanation
    The length of the label that goes around the outside of the can is equal to the circumference of the can. The formula for the circumference of a circle is 2πr, where r is the radius of the circle. Given that the radius of the can is 5.5 inches, the circumference can be calculated as 2 * 3.14 * 5.5 = 34.54 inches. Therefore, the correct answer is 34.54 in, 34.54 inches, 34.54in, 34.54inches, or 34.54.

    The trampoline below has a jumping mat that is 12 feet wide. What is the mat's area? - ProProfs

    The trampoline below has a jumping mat that is 12 feet wide. What is the mat's area?

    Explanation
    The area of a rectangle is calculated by multiplying its length by its width. In this case, the width of the trampoline's jumping mat is given as 12 feet. Therefore, to find the area, we multiply 12 feet by the length of the mat, which is not provided in the question. Without the length, we cannot calculate the area.
