Step-by-step explanation:
The formula of a surface area of a cylinder:
r - radius
H - height
We have r = 40mm and H = 50mm. Substitute:
Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet
Part A).
If 100 fish all had the same weight, and they weighed
235 pounds when they were all on the scale at the
same time, then each fish weighed
235 / 100 pounds .
Part-B).
You can find that actual weight with your calculator.
235 / 100 = 2.35 pounds .
Part-C).
If there were only 10 fish but their total weight was still 235 pounds,
then each fish would have to weigh a lot more, to make up the same
weight with only 10 of them.
Now, each fish would have to weigh 235 / 10 pounds .
That number is 235/10 = 23.5 pounds.
If there were only 1/10 as many fish, then in order to add up to the
same total weight, each fish would have to be 10 times as heavy.
