Answer:
251.20 cm square
Step-by-step explanation:
As given in figure
height of cylinder = 2 cm
radius of cylinder = 8 cm
lateral surface area of cylinder is given by = 
where r is the radius and l is the height
Therefore, lateral surface area of given cylinder
area of base is give by 
since there is only one base area of that base
= 
Thus,
Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
Answer:
The angle is 35 degrees
Step-by-step explanation:
Since this is an isosceles triangle, we know that the two remaining angles must be the same. Set those angles equal to x. Now, we can solve for x by adding those two angles to the third angle and setting equal to 180.
x + x + 110 = 180
2x + 110 = 180
2x = 70
x = 35
Set up your equation so that unit labels cancel out leaving you with the units needed for the solution...
300g(kg/1000g)($7.2/2kg)=$1.08
Answer:
39 square feet
Step-by-step explanation:
the area of a rectangle is equal to its base times its height.
we can break the two rectangles up and find their areas and then add the areas together for the final answer.
3 x 2 = 6
3 x 11 = 33
33 + 6 = 39
