That is the answer for the mean
Answer: The area is 9π unit squared ( in terms of π)
Step-by-step explanation:
From the equation for area of a circle, A = πr²
Where A is the area of the circle
r is the radius of the circle
From the question, the radius, r of the circle is 3
r = 3
Therefore, the Area of the circle is given by
A = π × (3)²
A = π×3×3
A = 9π unit squared ( in terms of π)
Hence, the area is 9π unit squared
OR
Since π is given as 3.14
Then,
A = 3.14 × (3)²
A = 3.14 × 3 × 3
A = 28.26 unit squared
Hence, Area is 28.26 unit squared (in decimal)
The doctor's cost for a set of scrubs is $47.60
Given:
cost = $34
mark-up = 40%
Mark up based on cost:
$34 * 40%/100% = $13.60 mark up
New price or doctor's cost:
$34 + 13.60 = $47.60
It can also be computed this way.
$34 * 140%/100% = $47.60
The answer should be -3/28
Area= length x width
Area = 12 x 80
Area= 960 in
