Answer:
height = 10.5 cm (for open-top container)
Step-by-step explanation:
The area of the base is ...
A = πr²
The lateral area is ...
A = 2πrh
We want the ratio of these to be 1:6, so we have ...
πr²/(2πrh) = 1/6
6πr² = 2πrh . . . cross multiply
h = 3r . . . . . . . divide by 2πr
h = 3(3.5 cm) = 10.5 cm
The height is 10.5 cm.
Answer:
y+6=9(x+4)
Step-by-step explanation:
point slope form is y-y1=m(X-x1)
y1 is -6
x1 is -4
And the slope or m is 9 so we can fill it in
y-(-6)=9(x-(-4))
y+6=9(x+4)
we can fill the equation out to see if it’s true
-6+6=9(-4+4)
0=9(0)
0=0
It is true

Answer:
(40π +48) cm²
Step-by-step explanation:
The total area is the sum of the areas of a 12 cm circle, a 4 cm circle, and a 12 cm by 4 cm rectangle.
For a given diameter (d), the area of a circle is ...
A = (π/4)d²
Then the area of the two circles is ...
A = (π/4)(12 cm)² +(π/4)(4 cm)² = (π/4)(144 cm² +16 cm²) = 40π cm²
The area of the rectangle is ...
A = LW
A = (12 cm)(4 cm) = 48 cm²
Then the total area of the figure is ...
total area = circle area + rectangle area
total area = 40π cm² +48 cm²
total area = (40π +48) cm²
