Answer:

y=140°

Step-by-step explanation:

Method 1.

The exterior angle theorem tells us that y=20+120=140

Method 2.

Solve for x first., then use that to solve for y.

The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.

y and x make a straight angle which is 180°, so we can get y by doing 180-40=140

The cylinder shown has a lateral surface area of about 80 square inches. Which answer is closest to the height of the cylinder?

Radda [10]

Hello!

The cylinder shown has a lateral surface area of about 80 square inches. Which answer is closest to the height of the cylinder? Use 3.14 to approximate pi.

We have the following data:

Al (lateral surface area) = 80 in²

R (ratio) = 4 in

h (height) = ? (in inches)

Adopt : π ≈ 3.14

We apply the data to the formula, we have:

$A_l = 2*\pi*R*h$

$80 = 2*3.14*4*h$

$80 = 25.12\:h$

$25.12\:h = 80$

$h = \dfrac{80}{25.12}$

$h = 3.18 \to \boxed{\boxed{h \approx 3.2\:in}}\:\:\:\:\:\:\bf\green{\checkmark}$

Answer:

≈ 3.2 inches
