At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. T

klio [65]

The formula for finding area of a circle is $\pi r^2$ .

Essentially, we have two circles here. One is a larger outer circle, and the other in a smaller inner circle. In order to find the area of the sidewalk, we must find the area of the outer circle, then find the are of the inner circle. After we find both areas, we subtract.

See attached image for process of finding area, and subtracting areas to find the final area of the sidewalk.

Find the similarity ratio and the ratio of perimeters for two regular octagons with areas of 18in2 and 50in2

sweet-ann [11.9K]

Answer:

3. 3 : 5; 3: 5

Step-by-step explanation:

First, let's find the leght of the sides of each octagon.

$A= 18in^{2}$

The area of an octagon is defined by

$A=2(1+\sqrt{2})l^{2}$

Replacing the area

$18=2(1+\sqrt{2})l^{2}\\\frac{18}{2(1+\sqrt{2})} =l^{2}\\l=\sqrt{\frac{18}{3.4} } \approx 2.3 \ in$

Therefore, the side of the first octagon is 1.6 inches long.

Its perimeter is: $P=8(2.3in)=18.4in$

$A=50 in^{2}$

$50=2(1+\sqrt{2})l^{2}\\\frac{50}{2(1+\sqrt{2})} =l^{2}\\l=\sqrt{\frac{50}{3.4} } \approx 3.8 \ in$

Therefore, the side of the second octagon is 3.8 inches long.

Its perimeter is $P=8(3.8in)=30.4in$ .

Now, let's divide to find each ratio:

$\frac{3.8}{2.3} \approx 1.65$ (the ratio between sides).

$\frac{30.4}{18.4} \approx 1.65$ (the ratio between perimeters).

Therefore, the closest ratio is 3. 3 : 5; 3: 5

(Please help I don't know how to do this)

mihalych1998 [28]

Answer: See step-by-step below.

Step-by-step explanation:

First we need to solve the equation, 16x + 16x - 1 = 10.

16x + 16x - 1 = 10

32x-1 = 10

Whatever we do on one side, we have to do on the other.

So, we will add 1 to both sides.

32x - 1 + 1 = 10 + 1

Simplify.

32x = 11

x = 11/32

So, 22x = 22(11/32)

= 121/16

= 7 9/16
