The statement that "The lengths of side SR and side S'R' are in the ratio 1:3" is correct.
The first option is incorrect because, as seen in the graph, the two angles have the same measure.
The second choice and third choices are wrong because the two polygons are different sizes, as stated in the question and as shown in the attached graph.
Therefore, the last selection is the correct option.
-2 * 1/4 = -1/2
-1/2 * 1/4 = -1/8
-1/8*8 1/4 = -1/32
Correct choice is the first one.
Answer:
The Lateral Surface Area is 911.32 square unit and
Total Surface Area is 1361.7 square unit.
Step-by-step explanation:
For a given Cone
Radius (r) = 12
Height (h) = 21
<u>For Lateral Surface Area</u>
<h3>
<u>Formula</u><u>:</u> </h3>
A = πr√r² + h²
A = 3.14 × 12 × √(12)² + (21)²
A = 3.14 × 12 × √144 + 441
A = 3.14 × 12 × √585
A = 37.68 × 24.18
A = 911.32 square unit
Now,
<u>For</u><u> </u><u>Total</u><u> Surface Area</u>
<h3><u>Formula:</u></h3>
A = πrl + πr²
For Slant height (l)
l² = r² + h²
l² = (12)² + (21)²
l² = 144 + 441
l² = 585
l = 24.18
So,
A = πrl + πr²
A = πr(l + r)
A = 3.14 × 12 × (24.14 + 12)
A = 3.14 × 12 × 36.14
A = 1361.7 square unit
Thus, The <u>Lateral Surface Area</u> is 911.32 square unit and <u>T</u><u>otal Surface Area</u> is 1361.7 square unit.

Step-by-step explanation:
calculator
Hello!
1.
find circumferece
c=2pir
c=2*6*pi=12pi
intercept is 5.4
2pi radians=all
part/whole=part/whole
5.4/12pi=x/2pi
times both sides by 12pi
5.4=6x
divide both sides by 6
0.9=x
answer is 0.9 radians
2.
assuming 9pi/5 radians
find circumference
c=2pir
c=2*26.9*pi
c=53.8pi
arc/circumference=(9pi/5)/2pi
x/(53.8pi)=(9pi/5)/(2pi)
x/(53.8pi)=18/5
times both sides by 53.8pi
x=608.46266 m
about x=608.46 m
Hope this Helps! Have A Wonderful Day! :)
