The circumference of a circle is 37.68 centimetres. What is the circle's radius? Use 3.14 for pi

Answer»

GIVEN :–

• Circumference of circle = 37.68 cm

TO FIND :–

• RADIUS of circle = ?

DIAGRAM :–

$\setlength{\unitlength}{20}\begin{picture}(6, 6) \<klux>PUT</klux>(1,1 ){\circle{14}} \put(1,1 ){\circle*{0.15}}\put(1, 1){\line(1,0 ){1}}\put(1.25,1.25 ){ $ \sf r $ }\put(2.5,1.5 ){ $ \sf circumference \: of \: the \: circle $ }\put(2.5, 1){ $ \sf = 37.68 \: cm $ }\put(3,0 ){ \boxed{ $ \bf @AK14380 $ }}\end{picture}$

SOLUTION :–

• We know that –

$\\ \dashrightarrow \large{\boxed { \bold{Circumference\:\:of\:\:circle= 2\pi r}}} \\$

• Put the values –

$\\ \implies { \bold{37.68= 2\pi r}} \\$

$\\ \implies { \bold{37.68= 2(3.14)r}} \\$

$\\ \implies { \bold{37.68= 6.28r}} \\$

$\\ \implies { \bold{r = \cancel \dfrac{37.68}{ 6.28}}} \\$

$\\ \implies { \bold{r =6}} \\$

• HENCE –

$\\ \implies \large { \boxed{ \bold{Radius =6 \: cm}}} \\$

Answer»

Answer:

Step-by-step explanation:

a) (107)²

⇒ [We have to use the identity: (a+B)²= a²+2ab+b².]

a=100 and b=7

(100+7)²= 100²+2 x 100 x 7+ 7²

= 100²+1400+7²

= 10000+1400+49

= 11449

b) 198 x 202

⇒ [We have to use the identity: (a-b) (a+b)= a²-b²]

a=200 and b=2

(200-2)(200+2)= 200²-2²

= 40000 - 4

= 39996

c)(1.01)²-(0.99)²

⇒ [We have to use the identity: a² – b² = (a + b)(a – b)]

a=1.01 and b=0.99

(1.01+0.99)(1.01-0.99)=(1.01)²-(0.99)²

=1.0201-0.9801

=0.04

d)1.01 x 0.99

⇒ (0.99)*(1.01)

= (1 - 0.01)*(1 + 0.01)

so (a+b)(a-b) = a^2 - b^2

= 1^2 - 0.01^2

= 1 - 0.0001

= 0.9999

e)998²

⇒ we should use the identity:(a + b)² = a² + 2ab + b²

a=900 and b= 98

(900+98)²=900²+2 x 900 x 98+98²

=900²+176400+98²

=810000+176400+9604

Answer» Answer: The least number that SUBTRACT from 4401624 is 20 to make them a perfect SQUARE of 2098. Step-by-step explanation: Hey Mate, Just find the roughly square ROOT of 4401624, Its nearly 2098.0049... So, if we find the 2098 square, so its a nearest value from 4401624. The square of 2098 is 4401604. So, we need to subtract (4401624 - 4401604 ) = 20 The least number that subtract from 4401624 is 20 to make them a perfect square of 2098.

Find the least number which must besub to make perfect square of 4 401624 ( ans in photo)

Answer»

Answer:

The least number that SUBTRACT from 4401624 is 20 to make them a perfect SQUARE of 2098.

Step-by-step explanation:

Hey Mate,

Just find the roughly square ROOT of 4401624, Its nearly 2098.0049...

So, if we find the 2098 square, so its a nearest value from 4401624.

The square of 2098 is 4401604.

So, we need to subtract (4401624 - 4401604 ) = 20

The least number that subtract from 4401624 is 20 to make them a perfect square of 2098.

Answer» Answer: 1/2 Step-by-step EXPLANATION: => 3x+5/5-x-2/3=5x-7/6 => 3x-x+1-2/3 = 5x-7/6 => 2x + 1 - 2/3 = 5x - 7/6 => 2x +(3-2)/3 = 5x - 7/6 => 2x +1/3 = 5x -7/6 => 2x - 5x = -7/6 - 1/3 => -3x = (-7 -2)/6 => -3x = -9/6 => -3x = -3/2 ..... ( 9 & 6 is divided by 2) => 3x = 3/2 ......( The negative SIGN is cancelled) => x = 3/(2×3) ..... ( Both 3s are cancelled ) => x =1/3. Hope the results is satisfactory

3x+5/5-x-2/3=5x-7/6

Answer»

Answer:

1/2

Step-by-step EXPLANATION:

=> 3x+5/5-x-2/3=5x-7/6

=> 3x-x+1-2/3 = 5x-7/6

=> 2x + 1 - 2/3 = 5x - 7/6

=> 2x +(3-2)/3 = 5x - 7/6

=> 2x +1/3 = 5x -7/6

=> 2x - 5x = -7/6 - 1/3

=> -3x = (-7 -2)/6

=> -3x = -9/6

=> -3x = -3/2 ..... ( 9 & 6 is divided by 2)

=> 3x = 3/2 ......( The negative SIGN is cancelled)

=> x = 3/(2×3) ..... ( Both 3s are cancelled )

=> x =1/3.

Hope the results is satisfactory
