<h2><u>Answer:</u></h2>

Pi = 3.14

Diameter (d) = 86 cm

•°• Radius (r) = 86 ÷ 2 = 43 cm (radius is 1/2 of diameter)

Area of the circle = ?

Formula,

\pi( {r})^{2}

Substitute the value of 'r' & pi in the formula.

\pi(43) {}^{2}  \\ =  3.14 \times 43 {}^{2}  \\  = 3.14 \times 1849 \\  = 5805.86  \:  \: cm {}^{2}

⎆ The area of the circle is about <u>5</u><u>8</u><u>0</u><u>5</u><u>.</u><u>8</u><u>6</u><u> </u>cm² (approx.)

What is the correct solution set for the following graph? graph showing two lines, labeled a and b, one atop the other
padilas [110]

Given:

Line a and line b

To find:

Which is the correct solution set for the graph.

Solution:

Here line a is on the line b.

So that a and b have same slope and same solution set.

For any graph of the line, the solution set is the points on the line.

Therefore the solution set is the infinite set of points on the line.

The correct solution set for the graph is infinite set of points on the line.

How to find angles on two Line intersect
Ivan
Hello!

Vertical angles are always congruent

This means that 3x - 35 = 130

We can solve this algebraically

3x - 35 = 130

Add 35 to both sides

3x = 165

Divide both sides by 3

x = 55

The angle AOB and AOC are supplementary which means they add to 180

First we have to find what angle AOB equals

3(55) - 35 = 130

We can subtract 180 by this number to get angle AOC

180 - 130 = 50

Angle AOC is 50

The answers are x = 55 and AOC = 50

Hope this helps!
