In order to find x, we first need to solve the ABC for side BC, then we can solve the right triangle from BC's length.
The left triangle is a 45-45-90. And the sides are:
y-y-y \sqrt{2}  \\ so \: x \sqrt{2} \: = 6 \sqrt{2}   \\ y(bc) =  \frac{6 \sqrt{2}}{\sqrt{2} }  = 6
for the right 30-60-90, the ratios are:
x - x \sqrt{3}  - 2x \\ so \: 2x = 6 \\ x = 3

A gumball is approximately spherical and has a diameter of 1 inch. What is the approximate volume of the gumball? A gumball is a
KatRina [158]

The approximate volume of the spherical gumball is: C. 0.5236 in.³.

<h3>How to Determine the Volume of a Spherical Shape?</h3>

If a shape is spherical, it means it has a shape of a sphere. To determine the volume of the spherical shape, we would use the formula for the volume of a sphere, which is given as:

Volume of a sphere = 4/3 × π × r³, where r (radius of the sphere) is half of the diameter of the sphere.

Given the following parameters of the sphere as:

Diameter of sphere = 1 inch.

Radius (r) = 1/2(1) = 0.5 inch.

π = 3.14

To find the approximate volume of the spherical gumball, substitute the value of r into 4/3 × π × r³:

Volume of the spherical gumball = 4/3 × 3.14 × 0.5³

Volume of the spherical gumball = 4/3 × 3.14 × 0.125

Volume of the spherical gumball = (4 × 3.14 × 0.125)/3

Volume of the spherical gumball = (1.57)/3

Volume of the spherical gumball = 0.523 in.³

Therefore, we can conclude that the approximate volume of the spherical gumball is: C. 0.5236 in.³.
