A circular mirror has a diameter of 12 inches. A circular frame that is 3 inches wide surrounds the mirror. What is the combined
soldi70 [24.7K]

Answer:

176.71 in^{2}

Step-by-step explanation:

The equation to use to find the radius of a circle is r = \frac{d}{2}

The equation to use to find the area of a circle is A = \pi r^{2}

First, add 3 inches to the diameter of 12 inches. You will get 15 inches.

Second, you will want to find the radius. Substitute 15 for d. Solve to get the radius.

r = \frac{15}{2}

r = 7.5

The radius is 7.5 inches.

Next, you substitute 7.5 for r in the area equation. Solve to get the area.

A = \pi (7.5)^{2}

A = 176.71 in^{2}

Which two points lie on the circumference of this circle? A. (1.3,0.5) B. (2.5,1.5) C. (3.4, -0.2) D. (3.9,0.7) E. (6.0,-2.0)
liq [111]

Step-by-step explanation:

(x-2)²+(y+5)²=25

option C (3.4,-0.2)

LHS= (3.4-2)²+(-0.2+5)²

= (1.4)²+(4.8)²

= 1.96+23.04

= 25

option E(6,-2)

LHS= (6-2)²+(-2+5)² = 4²+(-3)² = 16+9 = 25

Which angle is between NM and PN? hellp
DerKrebs [107]
The angle that is between the segments NM and PN is the angle that their segments form. If we take away the side PM (in our heads), we can see that the angle formed is angle N, or angle PNM.
