Answer:

44

Step-by-step explanation:

to find circumference of a circle you need to multiple r (7 in here) with 2 and pi

therefore the answer is : 2x7x3 = 42 or 44 approximately

Answer:

C\approx44\: cm

Step-by-step explanation:

1) The Circumference of a Circle is its Perimeter given by C=2\pi r. In this case, signed by a red line.

2) And \pi \approx3.14 with the given radius of 7 cm

3) Hence,

C=2*3.14*7\Rightarrow C\approx44\: cm

find the difference between the sum of all eight positive intergral divisors of 66 and the sum of all eight positive integral di
katrin [286]

The difference between the sum of all eight positive integral divisors of 66 and the sum of all eight positive integral divisors of 70 is zero.

<h3>How to find the difference between the integral divisors?</h3>

First let's find the integral divisors. We can write 66 as a product of prime numbers as:

66 = 33*2 = 2*3*11

Then the integral divisors of 66 are:

2

3

11

2*3 = 6

2*11 = 22

3*11 = 33

1 (trivially)

66 (trivially)

The sum gives:

2 + 3 + 11 + 6 + 22 +33 + 1 + 66 = 144

For 70 we have:

70 = 7*10 = 2*5*7

Then the integral divisors are:

1

70

2

5

7

2*5 = 10

2*7 = 14

5*7 = 35

The sum gives:

1 + 70 + 2 +5 + 7 + 10 + 14 + 35 = 144

Then the difference between these two sums is:

144 - 144 = 0

Identify which of the twelve basic functions listed below fit the description given
DENIUS [597]

Answer:

b.\:\: y=\sin(x),y=\cos(x)

Step-by-step explanation:

The range of the sine and cosine functions is -1\le x\le1.

This means that the maximum value the basic sine and cone functions is 1 and the minimum value is -1.

This means that the two functions are bounded above and below.

The correct answer is B.

What is [(7x^3)(y^2)]^2/7 in radical form?
GuDViN [60]
Remember
x^ \frac{m}{n} = \sqrt[n]{x^m}
and
(zy)^m=(z^m)(y^m)
and
(x^m)^n=x^(mn)

so
((7x^3)(y^2))^ \frac{2}{7} = \sqrt[7]{((7x^3)(y^2))^2}=
\sqrt[7]{((7x^3)^2(y^2)^2)}=
\sqrt[7]{((7^2x^6)(y^4))}=
\sqrt[7]{((49x^6)(y^4))}=
\sqrt[7]{49x^6y^4}
