<GBC and <2 are vertical angles, so they are congruent.
m<GBC = m<2 = 27
Supplementary angles have measures that add to 180 deg.
The supplement of <GBC measures 180 - 27 = 153 deg.

A spherical tank holds about 7,234.56 cubic meters of air.

Inessa [10]

Answer:

The radius of the spherical tank is 12 meters

Step-by-step explanation:

In this question, we are tasked with calculating the radius of the spherical tank given the volume of air it can hold

Mathematically, the volume V of a sphere is 4/3 * pi * r^3

Thus, 7234.56 = 4/3 * 3.14 * r^3

7,234.56 = 4.19 * r^3

r^3 = 7234.56/4.19

r^3 = 1,728

r = cube root of 1,728

r = 12 meters
