Answer:
To calculate the radius of a circle by using the circumference, take the circumference of the circle and divide it by 2 times π.
The two formulas that are useful for finding the radius of a circle are C=2*pi*r and A=pi*r^2.
The diameter is 2 times larger than the radius
Step-by-step explanation:

Henrietta solved a rational equation by multiplying both sides by 
.She did not find the least common multiple of the denominators .If she had find the least common denominator which is 3x(x+2) then the question can have been simplified in more simpler form.
Henrietta can have got rid of denominator and then use the distributive rule .
So the first option
A:She could use the least common multiple of the denominator is right
Answer:
Step-by-step explanation:
The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:
The height is marked as 
inches. Thus, the volume of the prism is:
You would have to multiply the top and bottom of both fractions, to get equal number between them,
Answer:
No, her answer is unreasonable because 0.2 * 6 = 1.2
Step-by-step explanation:
Here in this question, we are trying to use an approximation to see if what was said to be the result of a calculation is reasonable as an answer.
Looking at her division, 2.76/6 = 0.19
To the nearest tenth , 0.19 is same as 0.2, now multiplying 0.2 by 6, what we have is 1.2 ( of which even 0.19 * 6 is expected to be less than this). we can see that this value is quite far from our expected answer of 2.76 which makes the answer an unreasonable one
Thus, the division 2.76/6 = 0.19 is not a reasonable answer
