Five Identical semicircles are arranged as shown.<br> Find the diameter of one circle
Arte-miy333 [17]

The diameter of one circle is 28 units

Find the diagram shown below:

Considering the semi-circle at the centre.

  • Let the unknown distance from the left be x:
  • Let the unknown distance from the right be y:

To get the value of "x"

x + 16  = 22

x = 22 - 16

x = 6

To get the value of "x"

16 +y  = 22

y = 22 - 16

y = 6

Diameter of one of the circle = x + 16 + y

Diameter of one of the circle = 6 + 16 + 6

Diameter of one of the circle = 28

Hence the diameter of one circle is 28 units

LSA=2(l+b)×h

LSA=2×14×3=84 m

2

Therefore, cost of painting = 84×60=Rs.5040.

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "57.8" was replaced by "(578/10)". 2 more similar replacement(s)

STEP1:

           289

Simplify   ———

Find if divergent/convergent: <br> a(sub n)=(n^2/sqr(n^3+4n)), if convergent, find the limit.
Delicious77 [7]
We are given the equation <span>an = (n^2/ sqrt(n^3+4n)) and asked to determine if the function is divergent or convergent. In this case, we find the limit of the function as n approaches infinity. 

an = </span><span> (n^2/ sqrt(n^3+4n))
lim (n to infinity ) = infinity / infinty: ;indeterminate

Using L'hopitals rule, we derive
</span><span>lim (n to infinity )  = 2 n / 0.5* ( </span><span>n^3+4n) ^-0.5 * (3 n2 +4) : infinity / infinity 

again, we derive

</span>lim (n to infinity )  = 2 (0.25) (( n^3+4n) ^-0.5))*(3 n2 +4) / 0.5* ( 6n + 4) :infinity / infinity 
<span> 
again, 
</span>lim (n to infinity )  = 2 (0.25) (6n + 4) / 0.5* ( 6)* 0.5 <span>(( n^3+4n) ^-0.5))</span> 

this goes on and the function is divergent
