What is the probability of flipping a coin 85 times and getting tails 30 times or fewer?
A. 99.8%
B. 33.2%
C. 95.9%
D. 0.4%

C

Step-by-step explanation:

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 !

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
