:') alright. Break down the composite shape into 2 separate shapes:
The radius of the semi-circle is 14/2=7cm
So the area of the semi-circle is (pi×7^2)/2=77cm^2 to 1 d.p.
The area of the rectangle is 14×20=280cm^2
280+77=357cm^2 is the area of the composite shape
integral of e^x (sinx +cosx)= e^x sin x + c
Answer:
Step-by-step explanation:
Hello,
<em>I would recommend that you checked the answers I have already provided as this is the same method for all these questions, and maybe try to solve this one before you check the solution.</em>
<u>At the beginning the area is 2100</u>
<u>After one year</u> the area will be
2100*(1-3.5%)=2100*0.965
<u>After n years</u> the area will be
So after 5 years the area will be
So rounded to the nearest square kilometer is 1757
Hope this helps
