The circumference of a circle is 15π centimeters. What is the area of the circle in terms of π? A. 7.5π cm2

Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.

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)

Consider circle o, where and . m∠bpd °. °.
