1 answer:

3 0

Move the decimal place so its in between the first 2 non zero numbers, then count the amount of spaces you moved the decimal
6400000
6.400000
I moved it 6 spaces so it would be 10^6
6.4x10^6

Rudik [331]

The price of the one notebook will be Rs. 10.6

Let the price of one notebook be x.

If Haseena bought 1 pencil box, 4 pencils and 4 notebooks from a store, with a total of Rs. 95 paid in all, then;

1x + 4x + 4x = 95

9x = 95

x = 95/9

x = 10. 6

Hence the price of the one notebook will be Rs. 10.6

The formula for the volume of a cone is V=1/3(3.14)r^2(h) where V represents the volume, r represents the radius of the base, an

jasenka [17]

The original formula for the volume of a cone is

$V=\dfrac{1}{3}\pi r^2h$

O.K. You give the approximate value of pi in the formula.

$V=\dfrac{1}{3}\cdot3.14r^2h$

We have:

$V=66\ cm^3,\ r=3\ cm$

Substitute:

$\dfrac{1}{3}\cdot3.14\cdot3^2h=66\\\\3.14\cdot3h=66\\\\9.42h=66\ \ \ \ |:9.42\\\\h\approx7\ cm$

Answer: 7 cm.
