Answer:

$\fbox{Surface area of cylinder = 282.6 sq. in.}$

Step-by-step explanation:

Given:

Shape of object = cylinder

height of cylinder= 4 inches

radius of cylinder= 5 inches

To find:

surface area of cylinder = ?

Solution:

we know that,

$surface \: area \: of \: cylinder =2\pi{rh} + 2\pi {r}^{2}\\Substituting \:the \:constant\: (π =3.14)\\and \:given\: data,\\2\pi{rh} + 2\pi {r}^{2} \: =\\ 2×3.14×5×4+2×3.14× {5}^{2} \\2\pi{rh} + 2\pi {r}^{2} = 125.6 + 157 \\ 2\pi{rh} + 2\pi {r}^{2} = 282.6\\ \fbox{Surface area of cylinder = 282.6 sq. in.}$ [/tex]

Step-by-step explanation:

Look at the values from high school athletes (the first row of numbers) to the values of college student athletes (the second row). Since we are only looking for male percentages, ignore the women's basketball

Take any of the college values, and divide it by the high school values. After this, multiply by 100 to get a percentage

Example, 56500 ÷ 983600 = 0.05

0.05 * 100 = 5%

You will get 5% for all males sports in this table

(ﾉ◕ヮ◕)ﾉ*:･ﾟ✧PLEQASE HELP QUICK!!!! What is the exact volume of cylinder with a height of 40 inches and a radius of 16 inches ___

Delicious77 [7]

I can't resist helping someone with magic (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

The formula for the volume of a cylinder is pi x r^2 x h.
That's 10240 x pi or 32169.91

Triangle RST is shown. What is the y-coordinate of the final image of vertex T after the triangle is reflected over the x-axis f

gavmur [86]

Answer:

R¹(-7, -3) , S¹(-2, -1), T¹(-5, 4)

Step-by-step explanation:

Step(i):-

From the graph, the points are R(-4,5), S(1,3),T(-2,-2)

First, the points are reflected over the x-axis then transform in to

(x,y)→(x,-y)

R(-4,5)→R¹(-4,-5)

S(1,3)→S¹(1,-3)

T(-2,-2)→T¹(-2,2)

Step(ii):-

Next, The points are shifted to 3 units left then the transform

(x,y)→ (x -3 ,y)

R¹(-4,-5)→ R¹(-4-3, -5) → R¹(-7, -5)

S¹(1,-3) → S¹(1-3, -3) → S¹(-2, -3)

T¹(-2,2) → T¹(-2-3, 2)→ T¹(-5, 2)

Step(iii):-

Now again the points are shifted to '2' units up then transform to

(x,y) )→ (x ,y+2)

R¹(-7, -5+2) → R¹(-7, -3)

S¹(-2, -3+2) → S¹(-2, -1)

T¹(-5, 2+2) → T¹(-5, 4)
