Answer:

33.2 inches²

Step-by-step explanation:

Steps to derive the answer

  1. we are going to first determine the radius from the circumference
  2. we would calculate the area

Circumference of a circle = 2nr

n = 3.14

r = radius

20.41 = 2x 3.14 x r

Divide both sides by (2 x 3.14)

r = 3.25 inches

Area of a circle = nr²

3.14 x  3.25² = 33.2 inches²

One side of a rectangle is 3 m more than the other. If the perimeter of the rectangle is 30 m, what are its dimensions? *
uranmaximum [27]

Answer:

the length— 6

width— is 9

Step-by-step explanation:

you said One side— 3m MORE

so we will consider the length Number as X

we will consider width As three plus X

- You want to know the Perimeter. So we have to

add.

— so the expression is 3+3+x+x+x+x = 30

it is then simplified to 6+4x= 30

then we should be able to find out the X  which is 6

when we substitute the values with dimensions, you will get

your final Answer

I hope This Helped!

Answer:

1. 30 student

2. 120 student's didn't vote

3. 7 quarters

Step-by-step explanation:

1. first, see how many games can be played:

45÷3 = 15

then, multiply the number of games by two because 2 students can play per game

15 • 2 = 30

2. first, figure out what percent of students did not vote:

  100 - 60 = 40%

  then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:

    300 • .40 = 120 student's didn't vote

3. first, find how much 9 dimes is:

   1 dime = $0.10

   9 dimes = 9 • $0.10 = $0.90

  then, find how much money kerry had:

   $2.65 - $0.90 = $1.75

   finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:

   1 quarter = $0.25

    $1.75 ÷ $0.25 = 7 quarters

Find the value of each variable using sine and cosine round your answers to the nearest tenth​
Fudgin [204]

9514 1404 393

Answer:

  r ≈ 19.0

  s ≈ 17.7

Step-by-step explanation:

The relevant trig relations are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

So, you have ...

  cos(43°) = r/26

  r = 26·cos(43°) ≈ 19.0

__

  sin(43°) = s/26

  s = 26·sin(43°) ≈ 17.7
