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:

$Area = A_2 - A_1$

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

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

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

$Area = 3.14 (25 - 4)$

$Area = 3.14 * 21$

$Area = 65.94$

If the measure of angle is 0 is7x/4, which statements are true?

gayaneshka [121]

Answer:

a) The measure of the reference angle is 45°

Step-by-step explanation:

Reference angle:

$\sf \dfrac{7\pi }{4} \ is \ in \ the \ fourth \ quadrant.\\\\ \text{Reference angle = 2$\pi - \theta$}\\$

$\sf =2\pi -\dfrac{7\pi }{4}\\\\ =\dfrac{8\pi }{4}-\dfrac{7\pi }{4}\\\\= \dfrac{\pi }{4}\\\\=\dfrac{180}{4}\\\\$

= 45°
