Answer:
V = 314
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 5
h = 12
Work:
V = 3.14(5²)(12/3)
V = 3.14(25)(4)
The volume of the cone is 311.1in³.
V = ⅓Bh where B = πr²
V = ⅓πr²h
V = ⅓(22/7)(5²)12
V = 0.33(3.142)(25)12
V = 311.1in³
65 + 65 = 130
360 - 130 = 230 degrees
The correct answer is 20x-1
