Answer:
216
Step-by-step explanation:
Given the figure.
And the perimeter in the ratio 4: 2: 1.
Perimeter of smallest circle = 
To find:
Area of shaded region.
Solution:
To find the area, we need to have radius first.
And radius can be calculated by the given perimeter.
Formula for Perimeter is given as:
Perimeter = 
Radius of smallest circle = 4 cm
Ratio of perimeter is equal to the ratio of the radii.
Radius of 2nd smallest circle by the given ratio = 8 cm
Radius of largest circle = 16 cm
Area of a circle is given the formula:
Area of the smallest circle = 
Area of the 2nd smallest circle = 
Area of the largest circle = 
Area of the shaded region = Area of largest circle + 2 
Area of 2nd smallest circle + 3 Area of smallest circle - 2 Area of smallest circle - 3 Area of 2nd smallest circle
Area of the shaded region = Area of largest circle - Area of 2nd smallest circle + Area of smallest circle = 
Put it in Desmos and look at the graph virtually so you can have a better idea
You would have to find out how many square feet the lawn is first:
70 x 50 = 3500 square feet
You are told that one pound = 200 square feet so use this to calculate how many pound you’ll need for 3500 square feet.
3500 square feet divided by 200 square feet = 17.5 pounds
Answer: 17.5 pounds
Answer:
The 40% marked up price of refrigerator is $1260.
Step-by-step explanation:
The cost price of the refrigerator = $900
Now, the mark up should be 40%
Calculating the markup on the cost price , we get
40 % of $900 = 
or, 40 % mark up = $360
Now, the Marked up cost = Cost Price + Marked up Price
= $900 + $360 = $1260
Hence, the 40% marked up price of refrigerator is $1260.
The perimeter of R is the same as the perimeter of L
