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

Answer:

$\frac{1}{2}x+\frac{6}{5}=\frac{3}{10}x+\frac{3}{20}$

$x=-5\frac{1}{4}$

$7x-3+10=2x-8+8x$

A random number generator app on your phone generates two numbers between 0 and 8. What is the probability that the first number

aev [14]

Answer:

1/27

Step-by-step explanation:

There are 9 numbers between 0 and 8. 3 of them are less than 3 (0, 1, and 2), and 1 of them is 6.

The probability is therefore (3/9) (1/9) = 1/27.
