Maslowich

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.
The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be x
Profit and Lost be y .

According to the Question :-

$:\implies$ 460 = x + y ( Profit)

$:\implies$ 400 = x - y ( Loss)

Adding both :-

$:\implies$ 460 + 400 = x + y + x - y

$:\implies$ 860 = 2x

$:\implies$ x = 860/2

$:\implies$ x = 430

Hence the Cost price of the watch is 430 .

Consider the ball that fits perfectly inside the cylinder. The volume of the ball is 3,052.08 cm3. What is the volume of the cyl

mixas84 [53]

We know that

[volume of a sphere]=(4/3)*pi*r³-------> r=∛[(3*Volume)/(4*pi)]
r=∛[(3*Volume)/(4*pi)]------> r=∛[(3*3052.08)/(4*pi)]----> r=∛729
r=9 cm

[volume of a cylinder]=pi*r²*h
r=9 cm
h=2*r----> 2*9 -----> 18cm
[volume of a cylinder]=pi*r²*h----->pi*9²*18---> 4578.12 cm³

the answer is
4578 cm³
