Answer:

The correct option is 4.

Step-by-step explanation:

Given information: r=10 cm, h=9 cm and l=13.5 cm.

The volume of right cone is

$V=\frac{1}{3}\pi r^2h$

Where, r is the radius of base and h is the height of the cone.

$V=\frac{1}{3}\pi (10)^2(9)$

$V=\pi\times 100\times 3$

$V=300\pi$

The volume of cone is 300π cm³, therefore option 4 is correct.

Hello!

The volume of a cone is Volume = 1/3πr²h.

V = 1/3π(10)²(9)
= 1/3π100(9)
= 1/3π900
= 300π cm³

Therefore, the volume of this right cone is 300π cm³.

Carrie is looking for a job cutting hair. One option is self-employment at The Belmont Salon, where she would pay $438 per month

DochEvi [55]

Answer:

She would have to do 219 haircuts in a month for the costs to be the same, which would be $428.

Step-by-step explanation:

To find this we take the costs of the first place.

$438

Next we can look at the costs of the second place using x as the number of haircuts she'd do.

Now we can set the two equal to each other to find the number of cuts.

438 = 2x

219 = x

You find yourself with 17 guilders( a gold coin) but you are planning on taking a trip to a country where the local currency is

3241004551 [841]

We are given

The current exchange rate is 2 guilders for every 3 florins

so,

2 guilders = 3 florins

now, we can find for 1 guilders

so, we get

$1guilders=\frac{3}{2} florins$

now, we can multiply both sides by 17

$17\times 1guilders=17\times \frac{3}{2} florins$

now, we can simplify it

$17guilders=25.5florins$

so, option-A........Answer

Answer:

Step-by-step explanation:

The supplementary angles to ∠x are adding to 180° and are ∠HGC and ∠BGA

If ∠DGE = 90° , then

∠CGD is also 90° because ∠DGE and ∠CGD are a linear pair and

∠HGC is also 90° because ∠DGE and ∠HGC are vertical angles
