Answer:

Seperate the shapes!

Step-by-step explanation:

CIRCLE

First we want to find the area of the circle which would be:

\pi r^{2}

3.14159265359 x 2^{2}

3.14159265359 x 4cm

= 12.5663706144cm^{2} /2 (must divide by two because it is half of a circle)

= 6.28318530718cm^{2}

RECTANGLE/SQUARE

Find the area of the square.

AREA = L x W

Length = 2cm + ?

Width = 6cm

To find the length we must use the diameter of the circle (which is the radius but times it by 2)

To find diameter: r x 2

= 2cm x 2

= 4cm

Length = 4 + 2 = 6cm

Width = 6 cm

Area (Length x Width) = 6cm x 6cm

= 36cm^{2}

TOTAL AREA:

Just add the area of the circle and the area of the square together.

Area total = 36cm^{2} + 6.28318530718cm^{2}

= 42.2831853072cm^{2}

* Also round your total answer to the nearest tenth or hundreth if needed to do so.

A swimming pool at a park measures 9.75 meters by 7.2 meters the area of the playground is one and half times that of the swimmi

ElenaW [278]

9.75 x 7.2 = 70.2
Swimming Pool Area: 70.2
The Park Area: 70.2 x 1.5 = 105.3
Total Area of both Swimming Pool & Park area: 70.2 + 105.3 = 175.5
Final Answer: 175.5

Question in picture A) 16/63 B)-16/63 C) 63/16 D) -63/16

Orlov [11]

ANSWER
$\tan(x + y) = - \frac{63}{16}$

EXPLANATION

We were given that,

$\csc(x) = \frac{5}{3}$

This implies that,

$\sin(x) = \frac{3}{5}$

We use the Pythagorean identity

$\sin^{2} (x) + \cos^{2} (x)= 1$
to get,

$\cos(x) = \sqrt{1 - ( { \frac{3}{5} })^{2}} = \frac{4}{5}$

We were also given that,

$\cos(y) = \frac{5}{13}$

This means that,

$\sin(y) = \sqrt{1 - {( \frac{5}{13}) }^{2} } = \frac{12}{13}$

This is because,

$0 < \: x \: < \frac{\pi}{2}$

$0 < \: y \: < \frac{\pi}{2}$

This angles are in the first quadrant so we pick the positive values.

$\tan(x + y) = \frac{ \sin(x + y) }{ \cos(x + y) }$

$\tan(x + y) = \frac{ \sin(x ) \cos(y) + \sin(y) \cos(x) }{ \cos(x) \cos(y) - \sin(x) \sin(y) }$

$\tan(x + y) = \frac{ \frac{3}{5} \times \frac{5}{13} + \frac{12}{13} \times \frac{4}{5} }{ \frac{4}{5} \times \frac{5}{13} - \frac{3}{5} \times \frac{12}{13} }$

$\tan(x + y) = - \frac{63}{16}$

The correct answer is D
