mario collected 3g seashells. jasmine collected 10 more seashells that mario. write the number of seashells they collected toget

Rufina [12.5K]

Answer:

Total seashells = (6g + 10) seashells.

Step-by-step explanation:

Given that Mario collected 3g seashells.

Given that Jasmine collected 10 more seashells that mario. It means she collected (3g+10) seashells.

It says to write the number of seashells they collected together in terms of g.

Total seashells = Mario's seashells + Jasmine's seashells.

Total seashells = 3g + (3g+10).

Total seashells = 6g + 10.

Hence, Total seashells = (6g + 10) seashells.

What is the length of the cylinder's height? Please help

raketka [301]

Answer:

Height = 9 cm which means Option C is the answer

Step-by-step explanation:

In the question we are given ,

Volume of cylinder = 225π cm³

Radius of cylinder = 5 cm

And , we have to find the height of cylinder .

We know that ,

$\longrightarrow \pink{ \boxed{Volume \: of \: Cylinder = \pi r {}^{2}h }} \longleftarrow$

Our solution starts from here :

$\longmapsto \: \pi \: r {}^{2} h = 225\pi$

Step 1 : Cancelling π with π :

$\longmapsto \: \cancel{\pi} \: r {}^{2} h = 225 \cancel{\pi}$

Step 2 : Substituting value of radius which is 5 cm in the formula :

$\longmapsto \: (5) {}^{2} \times h = 225$

$\longmapsto \: 25h = 225$

Step 3 : Transposing 25 to right hand side :

$\longmapsto \: h = \frac{225}{25}$

Step 4 : Cancelling 225 by 25 :

$\longmapsto \: \red{\boxed{h = 9 \: cm}}$

Henceforth , height of cylinder is 9 cm
