What is the volume of a cone that has a height of 10 feet and a base with a diameter of 2 and half feet?

1 answer:

6 0

Volume of a cone: 1/3 $\pi$ r²h
r is the radius (diameter ÷ 2) and h is the height.

Find the radius first using the diameter: 2 $\frac{1} {2}$ ÷ 2 = 1.25

Now plug in the numbers into the formula.

1/3 $\pi$ 1.25²10 = <span>16.4

The volume of the cone is 16.4 cubic feet.

Korvikt [17]

Answer:

78 + 52 + X + 54 = 180

130 + X + 54 = 180

X + 54 = 180 - 130

X = 50 - 54

X = -4

What is the perimeter of A ABC?

Advocard [28]

Answer: 11.4

Step-by-step explanation:

Using the distance formula,

$AC=\sqrt{(-3-1)^2 + (-1-2)^2}}=5\\\\AB=\sqrt{(-3-0)^2 +(-1-3)^2}=5\\\\BC=\sqrt{(1-0)^2 + (2-3)^2}=\sqrt{2} \approx 1.4\\\\\implies P \approx 5+5+1.4=\boxed{11.4}$
