Answer:
123 cm^2
Step-by-step explanation:
for the rectangles its
#1 5(4)=20 cm^2
#2 5(7)= 35 cm^2
#3 5(8) = 40 cm^2
for the triangles its
4(7)(.5)(2)= 28 cm^2
4(7)= 28 cm^2
I get the .5 from the triangle area formula
and since the triangles are equal I multiplied it by 2 again so the .5 cancels out.
in the end you add them all up which is 20+35+40+28 = 123 cm^2
22400 or 33
The correct answer is the expression of the volume of the sphere is ×π× and the expression of the volume of the leftover space is π××16 - ×π× .
Height of the given cylindrical can = 16 cms.
Diameter of the given cylindrical can = 16 cms.
Now a spherical ball just fits in this given cylindrical can. Thus the diameter of the ball is equal to the diameter of the can, equal to 16 cms.
Thus the expression of the volume of ball = ×π× = ×π×
Expression of the volume of the cylindrical can is π×× h = π××16
Expression of the leftover volume would be volume of can minus volume of the ball = π××16 - ×π× .
a) 294
b) 10
42minutes*7gallongs= 294 gallons in 42 minutes
