If the perimeter of one face of a cube is 22.4 cm, determine, to the nearest hundredth, its lateral surface area. *

1 answer:

5 0

22.4/4 = 5.6 cm

5.6^2 = 31.36 cm^2 per side

Since the later surface area only counts for 4/6 sides on the cube, (31.36)(4) = 125.44 cm^2

Use the point-slope equation to identify the slope and the coordinates of a point

ioda

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 4 = $\frac{1}{2}$ (x - 1) ← is in point- slope form

with slope m = $\frac{1}{2}$

and (a, b) = (1, 4 ) ← point on the line
