Answer:
C
Step-by-step explanation:
there is the ground line of about -5.5 to +5.5 = 11 ft.
then the 2 walls of 7 ft height = 14 ft.
that is already 25 ft.
the 2 roof sides are both a little bit longer than the corresponding ground line of 5.5ft.
so, estimated about 6ft per roof side. that adds 12 ft.
so, we are at about 37 ft.
and the closest answer is C. 36 ft.
in actual numbers a roof side is (using Pythagoras) :
roof side² = 2.5² + 5.5² = 6.25 + 30.25 = 36.5
roof side = 6.041522987... ft
so, the actual perimeter is
25 + 2×6.041522987... = 37.08304597... ft
(-5, 3)
Hope this helps!!!

Step-by-step explanation:
the volume of the composite figure is . Correct option D)
<u>Step-by-step explanation:</u>
Here we have , The figure is made up of a cylinder and a sphere which has been cut in half. The radius of each half sphere is 5 mm. We need to find What is the volume of the composite figure . Let's find out:
We know that Volume of figure is :
⇒ Volume of cylinder + Volume of hemi-sphere
⇒
⇒
Putting values of h= 10 mm , r = 5 mm( Not given in question ! Searched in correct question )
⇒
⇒
⇒
Therefore , the volume of the composite figure is . Correct option D)
