A=4ℼR2 solve for R SHOW ALL STEPSSSSSSSSSSSSS

Mathematics

GuDViN [60]3 years ago

Given problem;

  A  = 4 π R²

  To solve for R, we have to make it the subject of the expression.

Since

      A  = 4 π R² , follow these steps to find R;

    Multiply both sides by \frac{1}{4\pi }  

 A x \frac{1}{4\pi }  =  \frac{1}{4\pi } x 4 π R²

          \frac{A}{4\pi }   = R²

Then find the square root of both sides

        √R²  = \sqrt{\frac{A}{4\pi } }  

            R  = \sqrt{\frac{A}{4\pi } }

The solution is \sqrt{\frac{A}{4\pi } }

Given the circle below secant kjI and tangent hi find the length of hi round to the nearest tenth if necessary.
garik1379 [7]

The length of the segment HI in the figure is 32.9

<h3>How to determine the length HI?</h3>

To do this, we make use of the following secant-tangent equation:

HI² = KI * JI

From the figure, we have:

KI = 21 + 24 = 45

JI = 24

So, we have:

HI² = 45 * 24

Evaluate the product

HI² = 1080

Take the square root of both sides

HI = 32.9

Hence, the length of the segment HI is 32.9

Carol wants to make a sculpture using brass and aluminum, with the dimensions shown below, Aluno Bree The area of the aluminum s
mars1129 [50]

The aluminum section's area formula solved for h is h =\frac{A}{a - b}

From the complete question, the expression of the area (A) in terms of variables a, b and h is:

A = ah - bh

Factor out h from the expression on the right-hand side

A = h(a - b)

Divide both sides of the equation by (a - b)

\frac{A}{(a - b)} = h

Remove the bracket

\frac{A}{a - b} = h

Rewrite the above equation as follows:

h =\frac{A}{a - b}

Hence, the aluminum section's area formula solved for h is h =\frac{A}{a - b}
