if the diameter of the circle above is 14 mm, what is the area of the circle?
7 mm2
49 mm2
196 mm2
14 mm2

I believe the correct answer is B. 49 mm2

because the r=7

then do the formula A=3.14*7²

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
