Use the rule to find the the first 10 terms in the pattern first term: 7 rule: multiply by 2

So,

Start with 7.

Multiply by 2.
7 * 2 = 14

Multiply by 2.
14 * 2 = 28

Multiply by 2.
28 * 2 = 56

Multiply by 2.
56 * 2 = 112

Multiply by 2.
112 * 2 = 224

Multiply by 2.
224 * 2 = 448

Multiply by 2.
448 * 2 = 896

Multiply by 2.
896 * 2 = 1792

Multiply by 2.
1792 * 2 = 3584

The first ten terms in the pattern are:
7, 14, 28, 56, 112, 224, 448, 896, 1792, 3584

In a function:
f(x) = 2x

In a rule:
S = {x| x/7 = Whole Number}

100π

Step-by-step explanation:

We have to find the height. Since we have the base and hypotenuse of the triangle, we can use the Pythagorean Theorem to find the side. We have c^2 - a^2 = b^2; 13^2 - 5^2 = 144; sqrt144 = 12. The height is 12 and the radius is 5, so using V = (1/3)πr2h, we get (1/3)π(25)(12) = 100π
