1 answer:
Answer:
707.9 cm³
Step-by-step explanation:
What is the volume of a spherical shell with inner radius 7 and outer radius 8?
The formula for the volume of a sphere is given as;
= 4/3 × π × r³
From the above question:
inner radius 7 and outer radius 8
Hence, the volume of a sphere with
inner radius 7 and outer radius 8 is calculated as:
V = (4/3 × π × 8³ ) - (4/3 × π × 7³)
V = 4/3 × π ×(8³- 7³)
V = 4/3 × π × (512 - 343)
V = 4/3 × π × 169
V = 707.9055446 cm³
V = 707.9 cm³

This situation is a right triangle with the base measuring 18 and the hypotenuse 22. We are looking for x, the height up the pole that the wire is going to be attached to. We will use Pythagorean's Theorem to find the missing length.
and
. x^2 = 160 so x =
or 12.65 feet

An Integer is a whole number so you can take out B and C and the
is 6.5 so your answer is A
and 
. x^2 = 160 so x = 
or 12.65 feet
is 6.5 so your answer is A
