Find the surface area of a cylinder with a base radius of 2 cm and a height of 3 cm.
jek_recluse [69]

Answer: 62.8cm^2

Step-by-step explanation:

The surface area of a cylinder is calculated by 2πrh+2πr2

where π is a constant, given as 3.14; h is the height, given as 3cm and r is radius, given as 2cm.

Therefore, rh = 3 x 2= 6 cm ^2 while r^2 =2 × 2= 4 cm^2.

Slot the values into the formula:

V= 2 (3.14) x 6 + 2 (3.14) x 4

V=37.68 + 25.12

V=62.8cm ^2

I hope this helps

Which shows 0.124 in expanded form? A. ( 1 × 1 10 ) + ( 2 × 1 100 ) + ( 4 × 1 1000 ) B. 1 + ( 2 × 1 100 ) + ( 4 × 1 1000 ) C. 1
iren [92.7K]

Answer:

A. ( 1 × 1 / 10 ) + ( 2 × 1 / 100 ) + ( 4 × 1 / 1000 )

Step-by-step explanation:

A number is written in expanded form if it shows the sum of the values of the individual digits that make up the number.

To write 0.124 in expanded form, follow these steps:

<em>(i) Take the digits one after the other and multiply it by its value depending on its place. </em>

<em>Taking the first digit </em>- 0

The value is 0 unit, where a unit is 1

<em>Now multiply 0 by 1</em>

=> 0 x 1

=> 0

<em>Taking the second digit </em>- 1

The value is 1 tenth, where a tenth is 1 / 10

<em>Now multiply 1 by 1 / 10</em>

=> 1 x 1 / 10

<em>Taking the third digit </em>- 2

The value is 2 hundredth, where a hundredth is 1 / 100

<em>Now multiply 2 by 1 / 100</em>

=> 2 x 1 / 100

<em>Taking the fourth digit </em>- 4

The value is 4 thousandth, where a thousandth is 1 / 1000

<em>Now multiply 4 by 1 / 1000</em>

=> 4 x 1 / 1000

<em>(ii) Add the results obtained in (i) above</em>

=> (0 x 1) + ( 1 x 1 / 10) + (2 x 1 / 100) + ( 4 x 1 / 1000)

=> ( 1 x 1 / 10) + (2 x 1 / 100) + ( 4 x 1 / 1000)

Therefore,

0.124 in expanded form is  ( 1 × 1 / 10 ) + ( 2 × 1 / 100 ) + ( 4 × 1 / 1000 )
