Answer:

Width = 44.45 inches

Height = 25.00 inches

Step-by-step explanation:

(16x)^2 + (9x)^2 = 51^2

256x^2 + 81x^2 = 2601

337x^2 = 2601

x^2 = 7.718

x = 2.778

Width = 44.45 inches

Height = 25.00 inches

I think this is right

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator
Dahasolnce [82]

Answer:

Volume, V = 3367.6 cm³

Step-by-step explanation:

Given the following data;

Diameter = 18.6 cm

Radius = diameter/2 = 18.6/2 = 9.3 cm

Pie, π = 3.14

To find the volume of the sphere;

Mathematically, the volume of a sphere is given by the formula;

Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3}

Where;

r is the radius of the sphere.

Substituting into the formula, we have;

V = \frac {4}{3} * 3.14 * 9.3^{3}

V =  4.186666667 * 804.357

Volume, V = 3367.6 cm³
