Math Problem Statement

Find the missing dimension of a cone.

V = 566.77 m3, r = 9.5 m, h = Answer 5.997

Solution

To find the height hh of the cone, we use the formula for the volume of a cone:

V=13πr2hV = \frac{1}{3} \pi r^2 h

Given:

  • V=566.77m3V = 566.77 \, \text{m}^3
  • r=9.5mr = 9.5 \, \text{m}

Now, we can solve for hh:

566.77=13π(9.5)2h566.77 = \frac{1}{3} \pi (9.5)^2 h

Simplifying the equation:

566.77=13π(90.25)h566.77 = \frac{1}{3} \pi (90.25) h

566.77=13×3.1416×90.25×h566.77 = \frac{1}{3} \times 3.1416 \times 90.25 \times h

Now solve for hh:

566.77=94.67h566.77 = 94.67 h

h=566.7794.675.997mh = \frac{566.77}{94.67} \approx 5.997 \, \text{m}

Thus, the height hh is approximately 5.997m5.997 \, \text{m}.
