Answer:

r=14cm

Step-by-step explanation:

Curved Surface area of a cylinder=484cm²

Height=5.5cm

r=?

Curved Surface Area=2πrh

484=2×3.142×r×5.5

484=34.56r

r=484/34.56

r=14cm

Answer:

radius= 14

Step-by-step explanation:

curved surface area of cylinder = 484

height = 5.5

C.S.A = 2πrh

or, 484 = 2×22/7×r×5.5

or, 484×7 = 2×22/7×5.5×r

or, 3388 = 242×r

or, 3388/242 = r

or, 14 = r

Use the given information to prove that RSU=TSV
RoseWind [281]

Answer:

Statement,                                                        Reason

Given segment RV = segment TU,                 Given  

m∠R = m∠T,                                                      Given

Segment RS ≅ segment ST,                            Base angles theorem

ΔRSV ≅ ΔTSU,                                                 SAS rule of congruency

Segment SV ≅ segment SU,                          CPCTC

VU ≅ UV,                                                          Reflexive property

RU = RV + VU, TV = TU + UV,                          Addition of segments

RV + VU ≅ TU + UV,                                         Addition property of equality

RU ≅ TV,                                                           Transitive property of addition

ΔRSU ≅ ΔTSV,                                                  SSS rule of congruency

Step-by-step explanation:

Where:

SAS- Side Angle Side

CPCTC -Congruent Parts of Congruent Triangles are Congruent

SSS -Side Side Side

If you remove the last digit (one’s place) from a 4-digit whole number, the resulting number is a factor of the 4-digit number.
shutvik [7]

Answer:

  900

Step-by-step explanation:

We assume that your 4-digit number must be in the range 1000 to 9999. Clearly, any number ending in zero will meet your requirement:

  1000/100 = 10

  3890/389 = 10

However, the requirement cannot be met when the 1s digit is other than zero.

__

For some 3-digit number N and some 1s digit x, the 4-digit number will be

  4-digit number: 10N+x

Dividing this by N will give ...

  (10N+x)/N = 10 remainder x

N will only be a factor of 10N+x when x=0.

So, there are 900 4-digit numbers that meet your requirement. They range from 1000 to 9990.

Someone please help, i honestly don’t get how to find the angles
jeyben [28]
A.) the degrees inside the triangles are 50, 70, and 60. you know because 180-120=60
b.) you know that they are similar triangles because they have the same angle degrees.

im not sure if this is correct but i think it is :)
