Answer:

x = -68/7 (-9.71428571429)

Step-by-step explanation:

Solve for x

-18 - 16 = 7x+ 34

- 18 - 16 - 34 = 7x

-68 = 7x

x = -68/7

----------------------

check

-18 - 16 = 7 * (-68/7) + 34

-18 - 16 - 34 = -68

-68 = -68

the answer is good

X-18-16 = 7x + 34

Simplify:

X -34 = 7x + 34

Add 34 to both sides:

X = 7x + 68

Subtract 7x from both sides:

-6x = 68

Divide both sides by-6

X = -34/3 = -11 1/3

Answer:

Area of circle = 200.96 units²

Step-by-step explanation:

The formula to find the area of a circle is: πr², where r is the radius (which is half of the diameter)

So the diameter is 16 and of 16 is 8, which is the radius.

Sub it into the formula of a circle and you would get the area of a circle.

3.14 x 8²

Use calculator

Area of circle = 200.96 units²

Volume of a Sphere Formula: $\displaystyle V = \frac{4}{3} \pi r^3$

r is radius

Step-by-step explanation:

Step 1: Define

Identify variables

r = 8 ft

Step 2: Find Volume

Substitute in variables [Volume of a Sphere Formula]: $\displaystyle V = \frac{4}{3} \pi (8 \ ft)^3$
Evaluate exponents: $\displaystyle V = \frac{4}{3} \pi (512\ ft^3)$
Multiply: $\displaystyle V = \frac{2048}{3} \pi \ ft^3$
Estimate: $\displaystyle V = 2144.66 \ ft^3$
