Step-by-step explanation:
First off, we need to recognize that the formula for the volume of a sphere is .
Then, we can plug in our r values one at a time.
The volume for the sphere with a 6-inch radius is about 904.779.
The volume for the sphere with a 3-inch radius is about 113.097.
To find how much greater the larger sphere is, we simply create a ratio between the two numbers:
Do the division to find that the volume of the larger sphere is about 8 times the volume of the smaller sphere.
The measure of angle J is 19.8°, and the correct option is D.
<h3>What is the formula of cosine?</h3>The law of cosine or cosine rule in trigonometry is a relation between the side and the angles of a triangle. Suppose a triangle with sides a, b, c and with angles cosC.
The following formula is used to find the angle j is;
Triangle HIJ has side lengths h=12, i = 17, j = 7.
Substitute all the values in the formula;
Hence, the measure of angle J is 19.8°, and the correct option is D.
