Find the un know value diameter= 9.8 circumfrence=? radius=? it is question of pie

Mathematics
1 answer:
Monica [59]3 years ago
8 0

The radius is 4.9 and the Circumference is 9.8π

Step-by-step explanation:

<u>Data:</u>

Diameter = 9.8

Circumference = ?

Radius = ?

<u>Radius</u>

Radius is half of the diameter so radius = \frac{diameter}{2}

Radius = \frac{9.8}{2}

Radius = 4.9

<u>Circumference</u>

Circumference = 2πr

Circumference = 2π(4.9)

Circumference = 9.8π

Therefore, the radius is 4.9 and the Circumference is 9.8π

Keywords: Circumference

A box contains 4 bags of flour. The total mass of all 4 bags is 6kg. What is the mass of each bag in grams?
vovangra [49]

Answer:

1500 g

Step-by-step explanation:

To find the mass of each bag, we divide 6 kg by 4.

(6 kg)/4 = 1.5 kg

Now we convert 1.5 kg to g.

1 kg = 1000 g

1.5 kg * (1000 g)/(1 kg) = 1500 g

Select the correct word to describe the function. the equation y = startfraction 5 x cubed over 8 endfraction represents functio
balandron [24]

The functions and their descriptions are:

  • Polynomial: y = \frac{5x^3}{8} and y = 5x^3 + 8
  • Logarithm: y = 6 + 0.25\ln(x)
  • Exponential y = \frac{18}{1 + 6e^{-0.25x}}

<h3>How to describe the functions?</h3>

The functions are given as:

y = \frac{5x^3}{8}

y = 6 + 0.25\ln(x)

y = \frac{18}{1 + 6e^{-0.25x}}

y = 5x^3 + 8

The functions would be described based on the type of function they represent.

Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.

HELP PLEASE WITH PART A AND B!!!!!
Elden [556K]
<h2>a. Answer:</h2>

For this question we'll use the following method:

1. Let's subtract old value from new value

185$-160$ = -25$

The negative value implies that the price has decreased

2. Divide the result by the old value

25$/185$ = 0,1351

3. Convert this value to percentage:

0,1351 x 100 = 13,51%

Finally, by rounding to the nearest tenth:

13,5%

That means 13,5% decrease

<h2 /><h2>b. Answer:</h2>

1. Let's subtract old value from new value

77$-56$ = 21$

The positive value implies that the price has increased

2. Divide the result by the old value

21$/77$ = 0,2727

3. Convert this value to percentage:

0,2727 x 100 = 27,3%

Finally, by rounding to the nearest tenth:

27,3%

That means 27,3% increase
