Find the exact circumference of a circle with the given radius. 3¼ inches C = A.6.25π in. B. 6.5π in. C. 23.25π in.
2 answers:
Answer: B.
Step-by-step explanation:
The circumference of a circle is given by :-
, where r is the radius of the circle.
We are given that the radius of a circle is inches.
First we convert into improper fractIon, we get
Now, circumference of the circle will be :-
Hence, the exact circumference of a circle =

Answer:
The expression 7x represents the height of the container.
Step-by-step explanation:
From the question:
We are being informed that; if the length of the container is half of a foot longer than its width.
Let the width be x;
Then the length of the container can now be ; x+1/2
We all known that the volume of a rectangular prism is : V= l×w×h
here;
l = length
w = width
h = height
If we rewrite the given expression :
;
Then we factor we make a similar coefficient of the above equation, the remaining entities left in the parenthesis should be a linear term with a leading coefficient of 1 to match the expression for the length of the container.
i.e
Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.
