Find the area of the composite figure

Step-by-step explanation:

You're only finding half of a circle but since you have 2, it is possible to just do the area of a circle which is

3.5 x 3.5 = 12.25

Because the radius of your circle is 3.5m but there are 2 of them you subtract 7 from 18 which give you 11:

Then you multiply 11 by 7.

= 77

Then add it all together.

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
