What is the area of the fire pit? (Use 3.14 for pi.)

laila [671]

Answer:

$Area = 65.94$

Step-by-step explanation:

I will assume that the shaded region is the fire pit

Given

$R = 5$

$r = 2$

Required

Determine the area of the fire pit

First, calculate the area of the big circle.

$A_2 = \pi R^2$

Area of the small is:

$A_1 = \pi r^2$

The area of the pit is:

$Area = A_2 - A_1$

$Area = \pi R^2 - \pi r^2$

$Area = \pi (R^2 - r^2)$

$Area = 3.14 (5^2 - 2^2)$

$Area = 3.14 (25 - 4)$

$Area = 3.14 * 21$

$Area = 65.94$

Write the equation of the line that has a slope of -1/2 and a y-intercept at (0,6).

Evgesh-ka [11]

Answer:

Step-by-step explanation:

Use the slope- intercept formula:

$y = mx + b$

where m = slope and b = y-intercept.

Since we are told the slope is -1/2, this means m = -1/2

We are also told the y-intercept is at (0, 6) this means b = 6

So now we have the equation:

y = -1/2x + 6
