1 meter has 100 CENTImeters.

now, 85cm is not longer than 1 meter clearly, because 100 cm > 85 cm.

so one can say, that is 1 meter is longer by 15cm instead.

100 - 85 = 15.

Answer:

1 meter has 100 cm

85cm is less them 100cm

Do subtraction. Like this:

100cm -85cm=

The answer is 15cm

Also, the question should be the other way.

What is the volume of the composite figure? (Round to the nearest hundredth. Use 3.14 for Pi.)

Natasha2012 [34]

The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.

Step-by-step explanation:

The given is,

Composite figure is combination of a half sphere and cone

Both have a radius of 4 centimeters

The cone has a height of 15 centimeters

Step:1

Volume of composite figure = Volume of half sphere + Volume of cone

Step:2

Formula for volume of semi sphere,

$Volume of half sphere, V_{Half sphere} = \frac{2}{3} \pi r^{3}$

Where, r - Radius of Half sphere,

From given, r = 4 centimeters

$V_{Half sphere} = \frac{2}{3} \pi 4^{3}$

$= (0.6667) (3.14) (64)$ (∵ $\pi$ = 3.14 )

$V_{Half sphere}$ = 133.9733 cubic centimeters

Formula for volume of cone,

$Volume of cone, V_{cone} = \frac{1}{3} \pi r^{2} h$

where, r - Radius of cone

h - Height of cone

From given,

r = 4 centimeters

h = 15 centimeters

Volume of cone,

$V_{cone} = \frac{1}{3} \pi 4^{2}(15)$

$= (0.333333) (3.14)(16)(15)$ (∵ $\pi$ = 3.14 )

$V_{cone}$ $= 251.1997$ cubic centimeters

Step:3

Volume of composite figure = 133.9733 + 251.1997

Volume of composite figure = 385.17 cubic centimeters

Result:

The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.

Identify all of the following solutions of square root x+14+2=x

True [87]

First add 14+2 so you have sqrt(x) +14=x. Next subtract the 14 to the other side and square both sides, so you have x=x^2+28x+196. Now subtract the x, then use quadratic formula to get the two solutions for the way you have the question typed. However, since I recognize this as being a test question from your FLVS course that is not typed correctly with the parenthesis that will give you the wrong answer. A better idea would be to review through the examples in the lesson, try a few practice problems, then you can easily solve by isolating the square root on one side by itself, then squaring both sides.
