Answer:
4.5
Step-by-step explanation:
The equation of an area of a circle is A=πr² where r is the radius.
The radius is also half the diameter. So the radius of the quarter is 1.2
A=π(1.2)²
A=π(1.44)
A=4.52389
Answer:
Step-by-step explanation:
Given:
To write: the given expression using summation notation
Solution:
Summation notation helps to write a long sum as a single expression.
In the summation notation, the variable is called the index of summation.
Let denote a set of n numbers.
Then in summation notation,
Answer:
and .
Step-by-step explanation:
Given:
Angle lies in first quadrant.
Since, this does not mean that and , because it is the ratio of the and which is not necessarily the exact values of them. And also and values lie between and so it cannot be .
In order to find the exact values, we need to find the exact angle.
So,
As the angle lies in 1st quadrant.
Using the angle we can find the exact values for and .
Answer:
$35,640
Step-by-step explanation:
$55×6p×12d×9h=$35,640
$2.50(f) + $4(n) = Total Cost
$2.50(9) + $4(9) = Total Cost
$22.50 + $36 = Total Cost
$58.50 = Total Cost
