A circle with radius of 4 cm sits inside a circle with radius of 11 cm.

kap26 [50]

The area of the shaded region = 330 sq cm

Step-by-step explanation:

Given,

The radius of small circle (r) = 4 cm

The radius of large circle (R) = 11 cm

To find the shaded region

Formula

The area of circle of radius r = π $r^{2}$ sq cm

So, The radius of the small circle = π× $4^{2}$ sq cm = 16π sq cm

The radius of the large circle = π× $11^{2}$ sq cm = 121π sq cm

Hence the area of the shaded region = 121π-16π sq cm

= 105π sq cm

= 105 × $\frac{22}{7}$ sq cm = 330 sq cm

Clara has a lawn in front of her house as mapped on the coordinate plane. She wants to plant a bed of flowers between the points

Ronch [10]

Answer:

Look Below In the Explanation

Step-by-step explanation:

Point P has coordinates of (4,4) and point Q has coordinates of (4,-4).

Since both points have the same x-coordinates we can subtract point Q's y-coordinate from point P's y-coordinate.

I will set the equation up and try and figure this part by yourself. I hope you learned what to do from previous questions that are very similar to this that I answered.

4 - ( -4) = length of the bed of flowers

Hope that helps and maybe earns a brainliest!

Have a splendid day! :^)

Help!! Which of the following uses the reciprocal property to rewrite 12/x-3 = 20/x+3?

loris [4]

The reciprocal property is:

$\frac{x - 3}{12} = \frac{x + 3}{20}$

Solution:

Given that,

$\frac{12}{x - 3} = \frac{20}{x + 3}$

The reciprocal property is given as:

The reciprocal of a fraction is the numerator and denominator switched

$\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}$

Therefore,

$\frac{12}{x - 3} = \frac{20}{x + 3}$

By reciprocal property,

Switch the numerator and denominator of right side fraction as well as left side fraction

The we get,

$\frac{x - 3}{12} = \frac{x + 3}{20}$

Thus option C is correct
