Answer:
We are asked to solve for the lateral area of the cylinder and the formula is shown below:
Lateral area = 2*pi*r*h
We are also given with the area of the base such as:
Area of the base = 36pi square units
Area of the base = pi*r²
Solving for radius:
36pi = pi*r²
r=6 inches
Solving for the lateral area when height is 2 units:
Lateral area = 2*pi*6*2
Lateral area = 24pi inches²
The answer is the letter "B" 24 square units

Answer:
A=40, B=60, C=80
Step-by-step explanation:
180/7 to find what "1" would be in the ratio then multiply 20*2, 20*3, 20*4.
All you have to do is understand what fraction it is and reduce it. So first you have to figure out what the word reduce means and the word means another to figuring it out in its lowest terms and for example, your fraction 2/24 can be reduced in its simplest terms 1/12 and the way i did that was that i'd had to divide both the numerator and denominator by 2 because I know that both the numerator and denominator are divisible by 2 and so if you divide you get 1/16 and that's how you reduce fractions and so follow this procedure and you'll get everything correct.
Answer:
- one negative real root in [-5, -4]; two complex roots
- the complex roots cannot be isolated in the same way.
Step-by-step explanation:
A graphing calculator is a wonderful tool for this. It shows the one real root to be near -4.062, so between -5 and -4.
The value of the cubic at x = -5 is -315; at -4 it is +15, so the root is definitely between those values.
The one real root is isolated to being between (-5, -315) and (-4, 15). The complex roots are not isolated.
