Please help with by finding the surface area of numbers 122 to 124 which are the top one ands please read 125 a and 126 to find
Annette [7]
Surface area of cylinder is 2 (pi)rh+2(pi)r^2
this is the area of the side [(2 (pi)rh] and the two circles together [2 (pi)r^2]

122. r=24
h=15
2 (3.14)24×15+2 (3.14)24^2
6.28×24×15+6.28×24^2
2260.8+3617.28
5878.08mm

123. r=5
h=8
2 (3.14)5×8+2 (3.14)5^2
6.28×5×8+6.28×5^2
251.2+157
408.2cm

124. the surface area of a cylinder that has a hole is going to be
surface area of big cylinder-2small area circles (the holes) + the area of the holes sides

hopefully that isn't too confusing

big radius: 8
height: 14

little radius: 2.5
height: 14

2 (3.14)8×14+2 (3.14)8^2
6.28×8×14+6.28×8^2
703.36+401.92

1105.28in (area of big cylinder)

2 (3.14)2.5^2 (two small holes)
6.28×2.5^2
39.25in (area of holes)

2 (3.14)×2.5×14 (area of side)
6.28×2.5×14
219.8in

1105.28-39.25+219.8
1066.03+219.8

1285.83in total surface area

125. h=20
r=6 since diameter is a foot or 12 in, half of that is 6
2 (3.14)6×20+2 (3.14)6^2
6.28×6×20+6.28×6^2
753.6+226.08
979.68in

126. first radius= 10
first height = 6

second radius= 6
second height= 10

2 (3.14)10×6+2 (3.14)10^2
6.28×10×6+6.28×10^2
376.8+628
1004.8in (surface area of first cylinder)

2 (3.14)6×10+2 (3.14)6^2
6.28×6×10+6.28×6^2
376.8+226.08
602.88in (surface area of second cylinder)

1004.8-602.88= 401.92

the surface area of the cylinder with radius 10 and height 6 is GREATER that the surface area of the cylinder with radius 6 and height 10..

Match each statement in the proof with the correct reason.
Masteriza [31]

Answer:

See explanation

Step-by-step explanation:

<u>Definition of parallelogram:</u> Parallelogram is a quadrilateral with two pairs of parallel sides.    

<u>Definition of transversal (diagonal):</u> A line that cuts across two or more (usually parallel) lines.

<u>Definition of the same side interior angles:</u> These angles are located exactly as their name describes. They are "interior" (between the parallel lines), and they are on the same side of the transversal (diagonal).

<u>The same-side interior angles theorem</u> states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary

       Statement                          Reason

1. ABCD is a parallelogram  -  Given

2. \overline{AB}\parallel \overline {CD}                           -  Definition of parallelogram

3. \overline{AD} is a diagonal of \overline{AB} and \overline{CD} - Definition of diagonal

4.  \angle A and \angle D are the same side interior angles - Definition of same-side interior angles

5.  \angle A is supplementary to  \angle D - Same-Side Interior Angles Theorem

natka813 [3]

Answer:

Your answer is that the magazine would cost $1.33 per issue.

Step-by-step explanation:

There are 12 months in a year and we get one issue per month, so we need to divide the cost 15.96 by 12 to find out the price per month. Your answer is that the magazine would cost $1.33 per issue.

Answer:

-2,5 since it is in the same quadrant of -6,4 which Is the gym

Think about it this way. Imagine a graph in your head. Left is negative. Right is positive. Up is positive and down is negative. Think of the numbers as rise over run. Vertical then horizontal. Because the gym is negative then positive you would need a number that is to the left then up.

Hope this helped:)
