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

Which of the following statements are false?
VikaD [51]

well, a and d are true, and b is somewhat false...

angles that are both less than 90 degrees and higher than 0 have to add up to equal 90, not just be less than 90

c, is the same thing. Straight angles are 180 degrees, but supplementary means two angles add up to equal 180 degrees, not just one

so b and c may be true, im not sure

i know that a and d are true, therefore they are not the right answer
