Correct Answer: 7π
Explanation: Formular for circumference is 2πr. Since the diameter of the circle is 7 inches and you need the radius, you have to divide the 7 by 2. Once you have the radius, plug it in to the formula.

r = 7/2 = 3.5

(2)(3.5)π
= 7π

Answer:

B. 3

Step-by-step explanation:

To find the value of c, substitute the x and y values of the given point into x and y of the equation, then isolate c. Since that given point is (2,5), substitute 2 for x and 5 for y:

$(5) = -2(2)^2+8(2)-c\\5 = -2(4)+16-c\\5 = -8 + 16 - c \\5 = 8 -c\\-3 = -c\\c = 3$

Thus, c = 3.
