How to find the arc length (geometry)

Mathematics
1 answer:
andrew11 [14]3 years ago
5 0

Answer:

94.2

Step-by-step explanation:

Arc length is basically circumference.

Circumference formula: 2πr

All we need is the radius.

Radius = r

15 x 2 = 30 (diameter)

Then we are going to multiply by pi.

Arc length = 30π OR 94.2

sergey [27]

Answer:

Step-by-step explanation:

\displaystyle \Large \boldsymbol{} 5\cdot  \sqrt{3:2\sqrt{3-\sqrt{2} } }  =\\\\\\ 5\cdot  \sqrt{\frac{3}{2\sqrt{3-\sqrt{2} } } \cdot \frac{2\sqrt{3+\sqrt{2} } }{2\sqrt{3+\sqrt{2} } } } = \\\\\\5\cdot  \sqrt{\frac{6\sqrt{3+\sqrt{2} } }{4\cdot \sqrt{9-2} } }  =5\sqrt{\frac{6\sqrt{3+\sqrt{2} } }{2\sqrt{7} } }

But if the condition would be like this

\displaystyle \Large \boldsymbol{} 5\cdot  \sqrt{3:2\sqrt{3-\boldsymbol2\sqrt{2} } }  =\\\\\\5\cdot \sqrt{\frac{3}{2\cdot \sqrt{\underbrace{2+1-2\sqrt{2} \cdot \sqrt{1} }_{(\sqrt{2} -1)^2} } }} =\\\\\\5\cdot \sqrt{\frac{3}{2\cdot (\sqrt{2}-1) } } } = \\\\\\ 5\cdot  \sqrt{\frac{3}{2(\sqrt{2}-1 )}  \cdot \frac{\sqrt{2} +1}{\sqrt{2}+1 }}   =5 \sqrt{\frac{3}{2(2-1)} }  =\boxed{5\sqrt{1,5} }

Suppose the dimensions of a rectangle with a perimeter of 18 inches are quadrupled. Find the perimeter of the new rectangle in i
oee [108]

The new perimeter of the rectangle if the dimensions are quadrupled would be 72 inches.

<h3>What are the side lengths of the first triangle?</h3>

The perimeter is always obtained by adding all the sides. This means the possible side lengths of the original rectangle are:

  • 5 inches + 5 inches + 4 inches + 4 inches

<h3>What are the side lengths of the new triangle?</h3>

5 inches x 4 = 20 inches

4 iches x 4 = 16 inches

<h3>What is the new perimeter?</h3>

20 + 20 + 16 +16= =72 inches
