Answer:
34.7791 [unit²].
Step-by-step explanation:
1) area of the circle is:
πr²;
2) area of the regular polygon is:
6*r²√3*0.25=1.5√3r²;
3) the required area:
πr²-1.5√3r²=r²(π-1.5*√3)=64*(3.1415-1.5*1.7321)=34.7791
Answer:
The length of MN is 58 cm.
Step-by-step explanation:
In the given figure we can see that AM = MB
So, M is the mid point of AB.
Also, BN = NC ( Consider the given figure )
So, N is the mid point of BC.
Since M and N are the midpoints of AB and BC .
So, by mid segment theorem which sates that the segment joining the midpoints of any two sides of a triangle will be parallel to the third side of the triangle and half its length.
⇒ MN is parallel to AC
and



Thus , the length of MN is 58 cm.
Answer:
6x - 2
Step-by-step explanation:
f(2x) = 3(2x) - 2
f(2x) = 6x - 2
To find the width, divide the area by the length.
Width = 9/10 / 2/5
When dividing fractions flip the second one over and multiply:
Width = 9/10 x 5/2 = (9 x5) / (10 x 2) = 45/20 = 2 and 1/4 miles.
