Answer: 30 cm
Step-by-step explanation:
The volume of the composite solid is 17000 cm³. To find h, we must first subtract the volume of the half cylinder from the composite volume.
From the figure, AE = MK, and so the radius of the half cylinder is 10cm. The volume of the half cylinder is thus 
the volume of a cylinder. The volume of a cylinder is πr²h. So a half cylinder is 1/2 πr²h. This gives us a volume of 
.
Thus, the volume of the right prism is 17000cm³ - 4400cm³ = 12600cm³. Consider the cross-section ABKJ. If we multiply this by AE, we'll have the volume of the right prism.
The ABKJ is a trapezoid so it's area is 
. Thus the volume of the right prism is 
. This gives us 
, and thus h = 30 cm.
Surface area is the area of all the sides added up. If you were to unfold all the areas and make it flat (2-D), area is
.
Volume would be cubed because it's 3-D
Answer:
62
Step-by-step explanation:
because of vertical angles, then corresponding angles it is congruent to the 62 angle
Answer:
pls do mark my answer as the brainliest..........
Step-by-step explanation
portion of square empty = 256 - 153.86 = 102.14cm^2
Well, 10x4=40 because 10+10+10+10=40 and that means your answer must be 40 ones or you asked something else.
