Answer:

Option B is correct.

Step-by-step explanation:

Given a system of equations is shown below:

Equation A: 3c = d - 8

Equation B: c = 4d + 8

we have to tell the first step to eliminate the variable d.

To eliminate the variable d we have to make the coefficients of d equal in both the equations.

Equation A: 3c = d - 8

Equation B: c = 4d + 8

First step is to Multiply equation B by 3 to make equal coefficients.

Hence, option B is correct.

Find the lateral surface area of this
Ksenya-84 [330]

Answer:

A=157.07\ cm^2

Step-by-step explanation:

Given that,

The radius of a cylinder, r = 5 cm

Height of the cylinder, h = 5 cm

We need to find the lateral surface area of the  cylinder. The formula for the lateral surface area of the cylinder is given by :

A=2\pi r h

Put all the values,

A=2\pi\times 5\times 5\\\\=157.07\ cm^2

So, the lateral surface area of the cylinder is 157.07\ cm^2.
