Answer:
true
Step-by-step explanation:
5x + 4x = 9x
3y + 7y = 10y
8 + 34 = 42
Answer:
A. real numbers, rational numbers
Step-by-step explanation:
An integer is a whole number, -2/15 is not whole. It is real and rational.
They give the formula as:
Surface Area =<span> (2 • <span>π <span>• r²) + (2 • <span>π • r • height)</span></span></span></span>
However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder. Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the <span>(2 • <span>π • r • height) part of the formula.
So, r = 3 inches and height = 8 * 3 inches, the side area equals
2 * PI * r * height
2 * 3.14159 * 3 * 24 =

<span>
452.39 cubic inches which is the lateral area.</span></span></span>
The first and last one are the same the teo middle ones are the same. the two middle ones equal -20 and the last and first one equal 20. this is for the question above problem 3.2
