worty [1.4K]

Answer:

THIS IS YOUR ANSWER:

$area \: of \: spere \: = 4\pi \: r {}^{2} \\ 154cm {}^{2} = 4 \times \frac{22}{7} \times r {}^{2}$

$\frac{154 \times 7}{4 \times 22} = r {}^{2} \\ r {}^{2} = 12.25 \\$

$r = \sqrt{12.25} \\ r = 3.5cm$

General Formulas and Concepts:

<u>Pre-Algebra</u>

Distributive Property

<u>Algebra I</u>

Function Composition

Step-by-step explanation:

<u>Step 1: Define</u>

g(x) = 3x + 1

f(x) = 2x - 5

<u>Step 2: Find</u>

Substitute: g(f(x)) = 3(2x - 5) + 1
Distribute 3: g(f(x)) = 6x - 15 + 1
Combine like terms: g(f(x)) = 6x - 14

PLEASE HELP WILL MARK BRAINLIST!

Every single one of those polynomials factors. When factored, your expression looks like this: $\frac{(3x-7)(x+3)}{x+3)(x-2)} * \frac{(2x+7)(x+9)}{(3x-7)(2x+7)}$ . When you cancel the like factors out, what you're left with is this: $\frac{1x+9}{1x-2}$ . That means that b = 9, c = 1, and d = -2

Part a:-
The base of each triangle is 4 inches long.
Their height is 3/2 * 4 = 6 inches.

b
The combined area of the triangular faces = 4 * 1/2 * 4 * 6 = 48 sq ins

c
Surface area of the pyramid = 48 + area of base = 48 + 16 = 64 sq ins.
