Given:
The expression is
To find:
The expression which is equivalent to the given expression.
Solution:
We have,
It can be written as
Taking LCM, we get
The mixed fraction of this improper fraction is
So, the expression is equivalent to the given expression.
Therefore, the correct option is A.
Answer:
A= (b1+b2)/2 then multiplied by h.
h=2(A/b1+b2)
height is 6 centimeters
Step-by-step explanation:
For area formula, you would add the bases, divide by 2, then multiply by height
For height formula, you would divide the area by the sum of base one and two, then multiply by two. Using that formula, it would be 72/(16+8) which equals 3, then multiply by 2, equaling 6.
19.625cm squared because you have to divide the diameter by 2 to get the radius.
Area of circle = pi times radius times radius
= 3.14 times 2.5 times 2.5
= 19.625cm squared
