Answer:

Volume of hemisphere is equals to 1071.78666 cubic unit

Step-by-step explanation:

Given: radius of hemisphere=8 unit

A hemisphere is a 3-dimensional object that is half of a sphere.

Volume of hemisphere is equal to two thirds multiplied by pi multiplied by radius to the power 3.

<u>Formula:</u> Volume of hemisphere(V)=\frac{2}{3} (\pi)r^3 where r is the radius of the hemisphere and the value of pi is constant i.e, \pi=3.14

Now, substitute the value of r to find the volume of hemisphere,

Volume of hemisphere(V)= \frac{2}{3} \pi r^3 =\frac{2}{3} \cdot 3.14 \cdot (8)^3

∴ V=\frac{2}{3}\cdot 3.14 \cdot 512 =1,071.78666 cubic unit.

At a rock concert, the ratio of girls to boys is 3:7. If there are 360 more boys than girls, how many girls are at the concert?
bixtya [17]
You could understand the ration as parts: the total number of parts was 3+7=10.

So girls were 3/10 parts and boys 7/10 parts. The difference was 7-3=4 parts. this difference is equal to 360, so each part is 90 (4*90 =360).

so girls are "3 parts" and each part is 90, then the number of girls is 3*90=270.

Evaluate - 2/5- x + (-9/10) where x = 4/5.
zalisa [80]

Answer:

- 2  1/10

Step-by-step explanation:

-2/5 -x -9/10

Let x = 4/5

-2/5 - 4/5 - 9/10

Combine like terms

-6/5 - 9/10

Get a common denominator of 10

-6/5 * 2/2 - 9/10

-12/10 - 9/10

-21/ 10

Change this to a mixed number

10 goes into 21   2 times with 1 left over

-2 1/10

Find the oth term of the geometric sequence 5, -25, 125,
maxonik [38]

Answer:

-625

Step-by-step explanation:

Here we are basically multiplying each term by -5. So if you want two more terms, you would go like this...

5 × -5 = -25

-25 × -5 = 125

125 × -5 = -625

-625 × -5 = 3125

and so on!!!

Hope it helps and mark it as Brainliest if possible!!! Good Luck!!!
