Answer:
6 ft
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2
216 = 6s^2
Divide each side by 6
216/6 = 6s^2/6
36 = s^2
Take the square root of each side
sqrt(36) = sqrt(s^2)
6 =s
Each side is 6ft
V=hpir^2
tricky, they didn't give us radius
they just gave circiufmerece
c=2pir
25.12=2pir
divide by 2 both sides
12.56=pir
divide by 3.14 both sides
4=r
subsitutet
v=hpir^2
v=66pi4^2
v=66pi16
v=1056pi
v=3315.84 cubic inches
The volumes will be the same, because the heights are equal and the cross-sectional areas at every level parallel to the bases are also equal.
I got 11 Mexican and 16 American.
20 x 11 = 220
15 x 16 = 240
Which equals 460
Answer:
The equation would be y = 1/2x + 5
Step-by-step explanation:
To find this equation, we start by using point slope form, and then plugging the slope in for m and the point in at (x1, y1).
y - y1 = m(x - x1)
y - 7 = 1/2(x - 4)
And now we solve for y.
y - 7 = 1/2(x - 4)
y - 7 = 1/2x - 2
y = 1/2x + 5
