For a map a scale of 2 inches to 70 miles is used. If the distance on the map measures 1.8 inches what is the actual distance

63 miles

Step-by-step explanation:

2/70 = 1.8/x                           Cross multiply

2x = 70 * 1.8                          Combine

2x = 126                                Divide by 2

x = 126/2

x = 63

The actual distance is 63 miles.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
