the volume of a cone is 120 cubic centimeters. the height of the cone is 4.5 centimeters. determine the radius of a cone

kolbaska11 [484]

<h3> given:</h3>

$v = 120 \: {cm}^{3}$

$h = 4.5 \: cm$

the radius of the cone.

<h3>solution:</h3>

$r = \sqrt{3 \frac{v}{\pi \: h} }$

$r = \sqrt{3 \times \frac{120}{\pi \times 4.5} }$

$r = 5.04627 \: cm$

$r = 5.05 \: cm$

hence, the radius of the given cone is 5.05 centimeters.

PLEASE HELP ME WITH THIS MATH PROBLEM

m∠ A = 60°, m∠ A = 60°, m∠ A = 60° and the sum of the angles in the triangle is 180°

<h3>How to determine the angles</h3>

It is important to note that the sum of angles in a triangle equals 180°

The given structure is a triangle, thus, the angles sum up to 180°

m ∠ A + m ∠ B + m ∠ C = 180°

m∠ A = 60°

m ∠ B = 60°

m ∠ C = 60°

The sum of the angle in the triangle = 60° + 60° + 60° = 180°

Thus, m∠ A = 60°, m∠ A = 60°, m∠ A = 60° and the sum of the angles in the triangle is 180°
