Answer:

Option C

The Area Of Shaded Region is 50.2 cm²

Step-by-step explanation:

For A given Circle,

<u>For</u><u> </u><u>Small</u><u> </u><u>(</u><u>Non-Shaded</u><u>)</u><u> </u><u>Circle</u><u>:</u>

Diameter (d) = 6 cm

Radius = d ÷ 2 = 6/2 = 3 cm

For Area of Small (Non-Shaded) Circle

<h3><u>Formula</u><u>:</u></h3>

<u>A = πr²</u>

A = 3.14 × (3)² cm

A = 3.14 × 9 cm

A = 28.26 cm²

<u>For </u><u>A</u><u>r</u><u>e</u><u>a</u><u> </u><u>of</u><u> </u><u>Big</u><u> (</u><u>S</u><u>haded) Circle:</u>

Diameter (d) = 10 cm

Radius = d ÷ 2 = 10/2 = 5 cm

For Area of Small (Non-Shaded) Circle

<h3><u>Formula:</u></h3>

<u>A = πr²</u>

A = 3.14 × (5)² cm

A = 3.14 × 25 cm

A = 78.5 cm²

<u>For</u><u> </u><u>The</u><u> </u><u>Area</u><u> </u><u>Of</u><u> </u><u>Shaded</u><u> </u><u>Region</u>

Area of Big Circle - Area of Small Circle

78.5 cm² - 28.26 cm² = 50.24 cm²

Thus, The Area Of Shaded Region is

50.2 cm²

Really need to someone to break this down so I can understand it

Answer:

<u>Slope</u><u> </u><u>is</u><u> </u><u>4</u><u>/</u><u>3</u>

Step-by-step explanation:

Slope is the derivative of the equation:

y =  \frac{1}{3}  {x}^{2}  - 2x + 15 \\  \\  \frac{dy}{dx}  =  \frac{1}{3} (2x) - 2 + 0 \\  \\  \frac{dy}{dx}  =  \frac{2}{3} x - 2

At point (5, 7), x is 5:

\frac{dy}{dx}  =  (\frac{2}{3}  \times 5) - 2 \\  \\  \frac{dy}{dx}  =  \frac{10}{3}  - 2 \\  \\  \frac{dy}{dx}  =  \frac{10 - 6}{3}  \\    \\  \frac{dy}{dx}  =  \frac{4}{3}

Which equation represents a circle with a center at (2, –8) and a radius of 11?
snow_lady [41]
The equation of a circle is defined by:  (x - h)² + (y - k)² = r²  where
(h,k) represents the center of your circle and r = the radius

So (x - 2)² + (y + 8)² = 121 is your equation
