(6 points) A cylinder with open top with radius r and height h has surface area 8 cm2 . Find the largest possible volume of such a cylinder

Find the difference (8ab+a+2) - (3ab+6)

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)

If a is a nonzero real number then the reciprocal of a is
