?=x\\\\\frac{9}{11}=\frac{x}{22}\ \ \ |it's\ a\ proportion\ \ \ |cross\ multiply\\\\11\cdot x=9\cdot22\ \ \ \ |divide\ both\ sides\ by\ 11\\\\x=\frac{9\cdot\not22^2}{\not11_1}\\\\x=\frac{9\cdot2}{1}\\\\\boxed{x=18}

The question mark will be 18 as
the denominator x 2 (11 x 2 = 22) so 9 x 2 = 18

The area of circle B is 45x ____. The ratio of circle A to Circle B
Leokris [45]

Answer:

<h3>a) 3/4</h3><h3>b) 4:3</h3>

Step-by-step explanation:

Find the diagram attached.

Given the scale factor of circle A to circle B as 3/4

A:B = 3:4

Total ratio = 3+4 = 7

Area of bigger square A = 45sq. units;

The Total area can be gotten using the expression;

\frac{4}{7} \times x = 45 where;

x is the total area of both circles.

Get x;

\frac{4}{7} \times x = 45\\4x = 7 \times 45\\4x = 315\\x = \frac{315}{4}\\x =  78.75

Area of circle B = 78.75 - 45 = 33.75

Let the fraction required be y

45 * y = 33.75

y = 33.75/45

y = 3375/4500

y = 45/60

y = 3/4

Hence the area of circle B is 45 * <u>3/4</u> of circle A

b)The ratio of circle A to Circle B is expressed as;

Ratio = Area of circle A/Area of circle B

Ratio = 45/33.75

Ratio = 45 * 100/3375

ratio = 4500/3375

Ratio = 4:3

Hence the ratio of circle A to Circle B is 4:3
