Answer:

(A) 440 cm²

Step-by-step explanation:

Volume of a right circular cylinder  =  1100 cm²

πr2 h =  1100 cm³

Here r = 5

(22/7) ⋅ (5)2 ⋅ h  =  1100

h  = 2/7

Curved surface area of cylinder  =  2 πr h

 =  2 ⋅ (22/7) ⋅ 5 ⋅ (2/7)

=  440 cm²

So, the curved surface area of cylinder is  440 cm²

Answer:

  • (C) 440 cm²

Step-by-step explanation:

<u>Volume:</u>

  • V = πr²h

<u>Given r = 5 cm and V = 110 cm³, find h:</u>

  • 1100 = π(5²)h
  • 1100/25 = πh
  • 44 = πh

<u>Curved surface area:</u>

  • S = 2πrh = 2*5*πh = 10*44 = 440 cm²

Correct choice is C

Find the slope of the line that passes through (-37, 47) and (26, 32).
stiks02 [169]
(x1,y1) = (-37,47)
(x2,y2) = (26,32)

Now, m = (47-32) / (26+37)
m = 15 / 63
m = 5/21
So, the slope would be 5/21

Hope this helps!

John has a map that shows a rectangular park 1 1/4 cm : 8 yd. on the map, the width of the park is 2 1/2 cm. What is the parks a
Ber [7]

Answer:

16 yd.  This is the park's actual length.

Step-by-step explanation:

Write and solve an equation of ratios:

1 1/4 cm     8 yd

------------ = -----------

2 1/2 cm        x

Note that 2(1 1/4 cm) = 2 1/2 cm, so the above equation becomes:

 1       8 yd

----- = ---------

  2         x

Solving for x, we get x = 16 yd.  This is the park's actual length.
