To find the answer we can break the figure into two parts: a rectangle and a semi circle.
The perimeter of the rectangle:
(10+4)×2
=28 ft
The perimeter of the semi circle:
perimeter of a circle: 2×兀×radius
(The radius: 4/2)
We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.
[2(3.14)(4/2)] / 2
=6.28 ft
We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:
28+6.28-4
=30.28ft
Therefore the answer is 30.28ft.
Hope it helps!
A. 8.53 units is the length of the straight which is perpendicular to the straight line CD
Answer:
-3
Step-by-step explanation:
divide 7 on both sides -21/7 = -3
w=-3
[] Similar
-> The triangles are similar because they were "mirrored" by the...
[] SSS
-> ... by the SSS similarity theorem, the sides are...
[] Proportional
-> ... the sides are proportional.
[] AB/AC
-> Since the sides are proportional, dividing corresponding sides will leave us with the same number
[] For the last two I think I am missing some information as I do not have any numbers and know where they got 85 from.
Have a nice day!
