The radius of one sphere is twice as great as the radius of a second sphere.
(note: write the ratios as a comparison of the smaller to the larger.)
a. find the ratio of their surface areas.
b. find the ratio of their volumes.

Let radius of one sphere be r and radius of second sphere be r'.

As per the statement

The radius of one sphere is twice as great as the radius of a second sphere.

⇒r = 2r'

We have to find the ratio of their surface areas.

Surface area of sphere(A) is given by:

a.

Ratio of their surface areas:

Let A be the surface area of one sphere and A' be the surface area of second sphere.

 and

then;

⇒

⇒

⇒

⇒

b.

Find the ratio of their volumes.

Volume of sphere(V) is given by:

Let V be the Volume of one sphere and V' be the Volume of second sphere.

⇒ and

then;

⇒

V : V' = 8: 1

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
