What is the exact volume of a cylinder that has a height of 1.8 ft and a radius of 6.1 ft?

1 answer:

3 0

Cylinder area=height times area of base (area of base=area of circle)

height =1.8
radius=6.1
area of circle=pi times r^2

area of circle=pi times 6.1^2=37.21π
times height

1.8 times 37.21π=66.978π

volume=66.978π ft^3

180 lb 12 oz - 79.3 kg = ___________ kg

Brrunno [24]

Answer:

$180lb\ 12 oz - 79.3kg = 2.8kg$

Step-by-step explanation:

Given

$180\ lb 12\ oz - 79.3kg$

Required

Solve

First, convert 180lb to kg

$1lb \to 0.454kg$

$180lb \to 180 *0.454kg$

$180lb \to 81.7kg$ -- to 1dp

Next, convert 12oz to kg

$1oz \to 0.03kg$

$12oz \to 12 * 0.03kg$

$12oz \to 0.4kg$ --- to 1 dp

So, the expression becomes:

$180\ lb 12\ oz - 79.3kg$

$81.7kg + 0.4kg - 79.3kg$

$= 2.8kg$

Hence:

$180lb\ 12 oz - 79.3kg = 2.8kg$

Jen is 4/10 meters taller than her sister. Her sister is 9/10 meters tall. How tall is Jen?

mariarad [96]

Add 4/10 to 9/10.

9/10 + 4/10 = 13/10

Simplify 13/10 into a mixed number by subtracting 10 from the numerator and turning it into a whole.

13/10 ⇒ 1 3/10

<h2>Answer:</h2>

<u>Jen is </u><u>1 3/10 meters</u><u> tall.</u>

PLEASE HELP NEED ANSWER NOW!!!!<br> what is the graph of this function?

Shtirlitz [24]

Its the purple graph that looks like a upside down V because all the values are negative due to the "-" being outside the absolute value symbols.

you can also graph it as y=-|x|
