Answer: 1st,2nd, and 4th one
Step-by-step explanation:
Area of a circle = PI x r^2
Area of sheet = 22/7 x 18^2 = 1,018.29 square cm.
Area of small circle = 22/7 x 4.5^2 = 63.64 square cm.
There are 2 small circles so total area of the circles are 63.64 x 2 = 127.28 square cm.
Area of rectangle = l x w = 4 x 1 = 4 square cm.
Total area of cutouts = 127.28 + 4 = 131.28 square cm.
Area of sheet left, subtract area of cutouts fro area of sheet:
1018.29 - 131.28 = 887.01 square cm.
Round everything as needed.
Answer:
%
Step-by-step explanation:
Surface area of a human body is given by -

Taking integral on both sides, we get -

Since, the at most error in the surface area of a human body is
%
Substituting this in above equation, we get -
![\frac{dS}{S} \leq [0.425*0.02 + 0.725*0.02]\\\frac{dS}{S} \leq0.023\\](https://tex.z-dn.net/?f=%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq%20%5B0.425%2A0.02%20%2B%200.725%2A0.02%5D%5C%5C%5Cfrac%7BdS%7D%7BS%7D%20%5Cleq0.023%5C%5C)
Thus, the maximum error is surface area is equal to
%
