Answer:
Natasha gets 84
Step-by-step explanation:
Here, we want to know how much Natasha gets
Krutika gets 2 times as much as Natasha
If Natasha gets x, Krutika gets 2x
If Natasha gets x, Richard will get x/3 ( 3 times of this is what Natasha gets)
Now let us have a ratio;
K : N : R
2x : x : x/3
Multiply through by 3
6x : 3x : x
To get the amount Natasha gets, we add up all ratio; (6x + 3x + x ) = 10x
Natasha gets 3x of the total ratio
That will be;
3x /10x * 280
= 3/10 * 280
= 84
The surface area of a cylinder is the sum of the top + bottom + body, right?
The top and the bottom are circles with the same radius 3.5 . And we know that the area of a circle is r^2pi, (don't forget we have 2 circle, so, the answer must be multiplied by 2)
Now, the body: the body is just a rectangular with the width is the height of the cylinder and the length is the circumference of the circle.
The circumference = 2 r pi
the height is given
All you need to do is to calculate them and add them up. You need to work out to get the answer.
It's A. Move the decimal to the right four places to make one the whole number, and then multiply one by ten to the negative fourth power to write it in scientific notation. If you're given a small decimal, the exponent will be negative. If you're given a large number, the exponent will be positive.
