Is 1/3 bigger than 5/6

Answers

no because in 1/3 you get 2/6 so if you have 1/3 vs. 5/6 than you only have 1/3 containing 2/6 and we are looking for 5/6 so that is wrong. 5/6 is bigger that 1/3.

Make them both into 6ths. To do that, multiply 1/3 by 2/2.
1/3x2/2=2/6
No, 5/6 is bigger than 1/3 because it is basically only 2/6.

If a cylinder holds a volume of 100 cm3, and is 30 cm tall, which is the area of the bottom of the cylinder?

Answers

=πr2h

Area of circle
=πr2

=V/h
=100/30
≈3.33cm

Well, lets break this down.

Volume = area of base * height

we know that the volume is 100 and the height is 30 so we can work backwards

100 = b * 30

now divide both sides by 30

(100/30) = b * (30/30)

the height cancels itself out and we are left with...

base = 3.33

therefore your answer is 3.33 cm^2

rebeccas kitten weighed 2 pounds 3 ounces. A month later the kitten weighed 56 ounces. How much weight did the kitten gain in that month ?

Answers

1 pound equals 16 ounces.

Convert the weight from pounds to ounces.

2 pounds 3 ounces:

2 pounds x 16 ounces per pound = 32 ounces

32 + 3 = 35 total ounces

Now find the difference by subtracting:

56 ounces - 35 ounces = 21 ounces

The kitten gained 21 ounces ( 1 pound 5 ounces)

Sh now weighs 3.5 pounds she gained 21 ounces 1.3125 pounds

A 6cm section of plastic water pipe has inner diameter of 12cm and outer diameter of 15cm. find the volume of the plastic pipe not the hollow interior to the nearest hundredth

Answers

Answer:

The volume of the plastic pipe is 141 cubic centimetre

Step-by-step explanation:

Given:

The Length of the plastic water pipe = 12 cm

The inner Diameter of the plastic water pipe = 12 cm

The outer Diameter of the plastic water pipe = 15 cm

To Find:

the volume of the plastic pipe not the hollow interior to the nearest hundredth = ?

Solution:

The volume of the plastic water pipe can be found by using the volume of the cylinder formula

The Volume of the cylinder = $\pi r^2 h$

Where

r is the radius

h is the height

Radius r $= (diameter)/(2) = (15)/(2) = 7.5 cm$

On substituting the values

The Volume of the cylinder

= $\pi (7.5) (6)$

= $45 \pi$

= 141.37 cubic centimetre

= 141 cubic centimetre
