Answer:

\frac{22\pi }{3} \: m

Step-by-step explanation:

central \:  \angle  ( \theta)\: for \: major \: arc \\  = 360 \degree - 30 \degree = 330 \degree \\ radius \: (r) = 4 \: m \\ length \: of \: major \: \overset{\frown} {ACB}  \:   \\ =  \frac{ \theta}{360 \degree}\times 2\pi \: r \\  \\  = \frac{ 330 \degree}{360 \degree}\times 2 \pi \times 4 \\  \\  =  \frac{ 11 }{12}\times 2 \pi \times 4 \\  \\  =  \frac{22\pi }{3} \: m

y: 4 | 7 | 10|

so make points at (1,4) (2,7) and (3,10), and connect them to get the line

4x + 1

x: 1 | 2 | 3
----------------
y: 5 | 9 | 13

Make points at (1,5) (2,9) and (3,13)

IF they do not intersect yet, continue making points until they intersect. Make note of the point in which they intersect, and that is your answer

Find the radius of a circle that has an area of 6.76 cm². Use it for pi.
Inessa05 [86]

Answer:

<h2>radius = 1.47 cm</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

Area = 6.76 cm²

To find the radius substitute the value of the area into the above formula and solve for the radius

That's

6.76 = \pi \:  {r}^{2}

Divide both sides by π

We have

{r}^{2}  =  \frac{6.76}{\pi}  \\ r =  \sqrt{ \frac{6.76}{\pi} }

r = 1.46689291

We have the final answer as

radius = 1.47 cm

Hope this helps you
