Answer:

See explanation

Step-by-step explanation:

The lateral surface area of a cylinder is calculated using:

L.S.A = 2\pi \: rh

We have that the lateral surface area is about, 80 square inches.

Assuming the radius is 10 inches, then we substitute r=10, π=3.14 and solve for h.

80 = 2 \times 3.14 \times 10h

We solve for h to get:

h =  \frac{80}{2 \times 3.14 \times 10 }  =  \frac{4}{3.14}

h = 1.3inches

In triangle $DEF,$ $\angle D = 30^\circ,$ $\angle F = 60^\circ,$ and $EF = 6.$ Find $DE + DF.$ [asy] unitsize(2 cm); pair D, E,
sergey [27]

Answer:

Step-by-step explanation:

The answer to this question is 12+6sqrt3.

This is because of the 30, 60, and 90 degree rule. The rule states that the hypotenuse is equal to twice the length of the shorter leg, which is the side across from the 30 degree angle.

Using the rule you now know that DF is 12. Then use the Pythagorean Theorem to find the length of DE. 12^2=144, and 6^2=36. 144-36=108.

The square root of 108 simplified=6sqrt3.

Then you add them together and get 12+6sqrt3.

HELP!!<br> What is the equation of the circle shown in the graph?
ale4655 [162]

9514 1404 393

Answer:

  (x +6)^2 +(y -4)^2 = 36

Step-by-step explanation:

The center is (-6, 4) and the radius is 6. Putting those into the standard form equation, you have ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . center (h, k), radius r

  (x -(-6))^2 +(y -4)^2 = 6^2 . . . . numbers filled in

  (x +6)^2 +(y -4)^2 = 36 . . . . . . cleaned up a bit

If the perimeter of a square is 5 feet, how many inches long is each side of the square?
marysya [2.9K]
Well since we know that the perimeter of a square is four times the length of one of its sides. We just have to divide 5 by 4 to get the length of one side:

5feet /4 sides = 1.25 feet

And to finish off, we have to convert feet to inches:

<u>1 foot      </u>= <u>12 inches</u>
1.25 feet    x inches

x inches = 12 inches x 1.25 feet ÷ 1 foot
x inches = 15 inches

Therefore, each side is 15 inches long.

Hope this helps!
