Find the lateral surface area of a

balandron [24]

Answer:

15.1 mm²

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

(where r is the radius and h is the height)

Given:

r = 1.2 mm
h = 2 mm

Substitute given values into the formula:

⇒ Lateral surface area = 2π(1.2)(2)

= 4.8π

= 15.1 mm² (nearest tenth)

Help! this is in algebra 1

Scrat [10]

Answer: I have the pictures attached

Step-by-step explanation:

In order to graph this, we have to get it into this equation: y = mx + b, where m = slope and b = y intercept.

y = 3/2x - 4 is already in this form.

2y + 4 = 2 + 3x is not, so we have to isolate y

2y + 4 - 4 = 2 + 3x - 4

2y = -2 + 3x

2y/2 = -2/2 + 3x/2

y = -1 + 3/2x

y = 3/2x - 1

Okay, now graph it knowing your y intercepts and your slopes.
