The radius of a circle is 12.1 ft. Find the circumference to the nearest tenth}to the nearest tenth

Gnoma [55]

Answer:

76 ft

Step-by-step explanation:

Use the circumference formula, C = 2 $\pi$ r

Plug in the radius:

C = 2 $\pi$ r

C = 2 $\pi$ (12.1)

C = 76.0

So, the circumference is 76 ft

The value of x and y in both equations

Vlada [557]

There is no solution to this set that works for both equations. If you multiply the top equation by 2 and then add them together, the x and y numbers will cancel. This leaves you with 0 =1010, which is never true.

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (21, 13)

Point (3, 13)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(3-21)^2+(13-13)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-18)^2+(0)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{324+0}$
[√Radical] Add: $\displaystyle d = \sqrt{324}$
[√Radical] Evaluate: $\displaystyle d = 18$
