We are given numbers √9 and -7.
Square root 9 is a perfect square.
Square root 9 = 3.
So, if we add square root 9 and -7, we would get
√9 + -7 = 3 -7 = -4.
So, we got a negative whole number.
<em>A negative or positive whole number is called an integer</em>.
So, it's an integer.
<h3>Therefore, correct option is D. Integer.</h3>
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.

This is a multiplication problem, so you multiply 4 x 5 1/5. First change 5 1/5 into an improper fraction. Do this by multiplying the denominator and whole, then add the numerator. 5 x 5 + 1= 26. Improper fraction is 26/5. Now multiply 4 x 26/5. 4 x 26= 104. So it is 104/5. Now if you want a mixed number your answer is 20 4/5
