The area of the curved surface of a cylinder is 6160cm. The height of the cylinder is 10cm. What is the radius of the cylinder i

valina [46]

Answer:

r = 98 cm

Step-by-step explanation:

Formula for curved surface area = $2\pi rh$

where r = radius & h = height

Let the radius be 'r'.

According to the question ,

$6160 = 2 \times \pi \times r \times 10$

$= > 20\pi r = 6160$

$= > r = \frac{6160}{20\pi} = \frac{6160 \times 7}{20 \times 22} = 98cm$

for any numbers x,y [x=0 in(4) and y = 0 in (5)] and any positive integers m,n, the following holds:x^m · x^n=x^m+nProve number

AlladinOne [14]

Proved

Explanation:

To prove x^m · x^n=x^m+n, let's assign numbers to x, m and n

let x = 2

m = 3, n = 4

x^m · x^n = 2^3 . 2^4

x^m+n = 2^(3+4)

Solve each of the above seperately and comparew the answer:

$\begin{gathered} x^m\times x^n=2^3\times2^4 \\ =\text{ (2}\times2\times2)\times(2\times2\times2\times2) \\ =\text{ 8}\times16 \\ =\text{ }128 \end{gathered}$ $\begin{gathered} x^{m+n}=2^{3+4} \\ =2^7\text{ = 2}\times2\times2\times2\times2\times2\times2 \\ =\text{ 128} \end{gathered}$ $\begin{gathered} sincex^m\times x^n\text{ = 128} \\ \text{and x}^{m+n}\text{ = 128} \\ \text{Therefore, }x^m\times x^n\text{ = x}^{m+n} \end{gathered}$

This expression x^m · x^n=x^m+n has been proved to be equal

How can you classify the results of operations on real numbers? <br>

choli [55]

Closure property: If a and b are real numbers, a+b is also a real number.
- Associative property: a+(b+c) = (a+b)+c.
- Commutative property: a+b = b+a.
- Additive identity: a+0 = a.
- Additive inverse: a + (-a) = 0.
