The arc corresponding to a central angle of 125 degrees in a circle of radius 10 feet measures _____ feet. Round your answer to two decimal places.

Answers

Answer:

21.82\ ft

Step-by-step explanation:

we know that

The circumference of a complete circle is equal to

C=2\pi r

In this problem we have

r=10\ ft

substitute

C=2\pi (10)=20 \pi\ ft

Remember that

An angle of 360\° subtends the arc length of a complete circle

so

by proportion

Find the arc length for an angle of 125\°

(20 \pi)/(360)(feet)/(degrees)=(x)/(125)(feet)/(degrees)\n \nx=125*(20\pi )/360\n \nx=21.82\ ft
(Angle)/(360) x 2 \pi r

(125)/(360) x 2 \pi (10) = 21.82

Answer: The Arc measures 21.82 feet

18+18+6+6=48

x-12=x/3

Multiply both sides by 3

a chef uses 3 3/4 pounds of semolina flour and 1 5/8 pound whole wheat flour for each batch of pasta she makes.one week she uses a total of 86 pounds of flour WRITE AN EQUATION:

Answers

1 Pasta=(18)/(8)+(5)/(8)=(23)/(8 ) pounds of flour

We create a proportion:

1(pastas)=(23)/(8 )

X=86

86=(23)/(8 )x

86=2.875x

x=29.91

Chef will be able to make 29 Pastas and eat what's left :)

2/3 of the product of 3/8 and 16

Answers

finding the product of 2 numbers means that you have to multiply those numbers

(3)/(8) * 16

when multiplying fractions , numerators are multiplied by numerators and denominators by denominators

(3)/(8)*(16)/(1) = (3*16)/(8*1) = (48)/(8) = 6

therefore product of 3/8 and 16 is 6

next we have to find 2/3 of 6

'of' operator means multiplication

(2)/(3) *(6)/(1) = (2*6)/(3*1) = (12)/(3) = 4


answer is 4

4

Further explanation

The Problem:

  • (2)/(3) of the product of (3)/(8) and 16.
  • Write an expression to match and then evaluate.

The Process:

Here are some early expressions that need attention.

  • two-thirds is (2)/(3)
  • three-eights is (3)/(8)
  • the product of (3)/(8) and 16 is (3)/(8) * 16

The term of "the product" is synonymous with multiplication.

Let us write an expression to match for (2)/(3) of the product of (3)/(8) and 16.

\boxed{\boxed{ \ (2)/(3) * \bigg( (3)/(8) * 16 \bigg ) \ }}

And now we evaluate the full expression.

\boxed{ \ = (2)/(3) * \bigg( (3)/(8) * 16 \bigg ) \ }

We can cross out 8 and 16.

\boxed{ \ = (2)/(3) * (3 * 2) \ }

\boxed{ \ = (2)/(3) * 6 \ }

We can cross out 3 and 6.

\boxed{ \ = 2 * 2 \ }

Thus, the result is 4.

Quick Steps:

\boxed{ \ (2)/(3) * (3)/(8) * 16 \ }

\boxed{ \ (1)/(1) * (1)/(4) * 16 \ }

\boxed{ \ (16)/(4) \ or \ 16 / 4 \ }

\boxed{\boxed{ \ 4 \ }}
