Volume of a hemisphere formula?

1 answer:

8 0

To find the volume of a sphere you use...

V = 4/3 pi r^3

"Hemi-" means half. So we would divide by 2.

V= (4/3 pi r^3) / 2

A baseball team had 70 players show up for tryouts last year and this year had 85 players show up for tryouts. Find the percent

Mashutka [201]

Answer:percent increase in players from last year to this year= 7.14%

Step-by-step explanation:

percent increase = (Increase in number of players /Initial value of players Last year) x 100

value of players for tryouts last year = 70

value of players for tryouts this year = 85

Increase in tryouts = 85-70 =5

percent increase = 5/70 x 100

= 7.14%

How many cubes with side lengths of 1/3 cm does it take to fill the prism?

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer

Using exterior angle formula, you get that ∠CAD=36+123=159°

Exterior angle formula says that the angles facing CAB (ACB and ABC) sum to CAD.
