Answer:

area of this circle: 490.6 inch²

Step-by-step explanation:

area of circle: π(radius)²

Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in

using the formula:

3.14(12.5)²

490.625 inch²

490.6 inch²____rounded to nearest tenth.

<h3>Given:</h3>

\\

  • Diameter of circle = 25in.

\\

<h3>To find:</h3>

\\

  • Area of circle.

\\

<h3>Explanation:</h3>

\\

So as Diameter is given , let's covert it into radius.

We know:

\\

\bigstar \boxed{ \rm Diameter \: of \: circle \:  = 2 \times radius}

\\ \\

\hookrightarrow \sf Diameter \: of \: circle \:  = 2 \times radius \\

\\  \\

\hookrightarrow \sf 25 = 2 \times radius \\

\\  \\

\hookrightarrow \sf radius \:  =  \dfrac{25}{2}

\\  \\

\hookrightarrow \bf radius \:  = 12.5 in.

Now Let's find circumference of circle:

we know:-

\\  \\

\bigstar \boxed{ \rm Circumference \: of \: circle \:  =  \pi radius^2}

\\

So:-

\\  \\

\dashrightarrow \sf Circumference \: of \: circle \:  =  \pi radius^2\\

\\  \\

\dashrightarrow \sf Circumference \: of \: circle \:  = 3.14\times (12.5)^2\\

\\  \\

\dashrightarrow \sf Circumference \: of \: circle \:  = 3.14 \times 156.25\\

\\  \\

\dashrightarrow \bf Circumference \: of \: circle \:  = 490.63\\

\\  \\

\bf\dag \underline {\blue{\frak{ Circumference \: of \: circle \:  = 490.63 in(approx)}}}

Amy gets a new kennel for her dog. A sketch of the kennel is shown here. If the roof is in the shape of a triangular prism (bott
SpyIntel [72]

Answer:

<em>Surface area of the roof of the kennel, including the bottom face is 58.96 ft^2</em>

<em></em>

Step-by-step explanation:

The image is attached below

For the triangular sides of the roof, area is

A = \frac{1}{2}bh

where b is the base = 4 ft

h is the vertical height = 2.24 ft

A =  \frac{1}{2}*4*2.24 = 4.48 ft^2

for the two faces we have 2 x 4.48 ft^2 = <em>8.96 ft^2</em>

For the rectangular sections of the roof, area is

A = lh

where l is the length of the rectangle = 5 ft

h is the height of the rectangle = 3 ft

A = 5 x 3 = 15 ft^2

For the two rectangular faces, we have 2 x 15 ft^2 = <em>30 ft^2</em>

<em></em>

For the bottom face, area is

A = lw

where l is the length of the house = 5 ft

w is the width of the house = 4 ft

A = 5 x 4 = <em>20 ft^2</em>

<em></em>

Surface area of the roof of the dog kennel is

<em>8.96 ft^2 + 30 ft^2 + 20 ft^2 = 58.96 ft^2</em>

Jonathan uploaded some original songs and also some pictures. alissa uploaded four times as many songs, but only uploaded twice
lesya [120]

X is the number of songs and Y the number of pics

our 2 equations will be - X+y=11 & 4x+2y=24

consider x=11-y

Lets replace x in 2:

=4(11-y) +2y=24

=44-4y+2y=24

=44-24= 4y-2y

=20= 2y

=Y=20/2

=Y=10

Lets replace y in 1

=X+10=11

=X=11-10

=X=1
