Mathematics
1 answer:
Burka [1]3 years ago

Answer:

OPTION C: 300$ \pi $ cm³

Step-by-step explanation:

Volume of a cylinder = $ \pi r^2 h $

where, $ r $ - is the radius of the cylinder;

and      $h $ - is the height.

Given: $ r = 5 cm $ and $ h = 12 cm $

⇒ V = $ \pi $ (5)² (12) = $ \pi $ (25) (12)

⇒                          V = 300 $ \pi $

Therefore, the volume of the cylinder, V = 300$ \pi $ cm³.

Find the surface area and show work
Law Incorporation [45]

Answer: 1,270in^2

Step-by-step explanation:

The surface area of a rectangle can be calculated with:

Area_{rectangle}=lenght*width

The surface area of a trapezoid can be calculated with:

Area_{trapezoid}=\frac{height}{2}(Larger\ base+Smaller\ base)

Calculate the area of the base, wich is a rectangle:

A_{1}=(34in)(15in)=510in^2

There are two equal rectangles, therefore, multiply the area of any of them by 2:

A_{2}=2(15in)(13in)=390in^2

Calculate the area of the other rectangle:

A_{3}=(15in)(10in)=150in^2

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

A_4=\frac{2(5in)}{2}(34in+10in)=220in^2

Therefore, the surface area will be the sum of all the areas calculated:

SA=A_1+A_2+A_3+A_4\\\\SA=510in^2+390in^2+150in^2+220in^2\\\\SA=1,270in^2

matrenka [14]
If 3 = m^x, then we know 9 = (m^x)^2 because 9 is 3 squared.

(m^x)^2 can be simplified to m^{2x}

So now we know 9m^2 = m^{2x}·m^2

Since m^{2x} and m^2 have the same base, we can express it as a single term by adding the exponents together.

So the answer is C) m^{2x+2}
