Let h(x)=|2x|-4. Find h(x) when x = -7.
a)-10
b) 10
c) -13
d) 13
Plzzz

first, you need to find the radius. if it isn't provided, divide the diameter by two or the circumference by two pi. secondly, you need to use the radius to find the base area of the circle. use a=pi*r^2 to find the area of the base circle. then, you need to find the height of the cone. next, multiply the area of the base by the height of the cone. then divide your product by three.

there's your final answer.
