Find the circumference of the circle. Round your answer to the nearest hundredth. Use 3.14 or pi circle is 3 ft in radius

densk [106]

Answer:

18.84 feet

Step-by-step explanation:

The circumference of a circle can be found using:

c=π*d

The radius is given, but we have to find diameter. The diameter is twice the radius, or

d=2r

The radius is 3 feet. Substitute 3 in for r.

d=2*3

d=6

The diameter is 6 feet.

Now we have the diameter. We can substitute 6 in for d in the circumference formula. We can also substitute 3.14 in for pi.

c=π*d

c=3.14*6

c=18.84

The circumference is 18.84 feet

If √2 = 1.414 then the value of 5+√2 / 5-√2 is

Gala2k [10]

Answer:

1.787

Step-by-step explanation:

$\\ \sf \frac{5 + \sqrt{2} }{5 - \sqrt{2} } \times \frac{5 + \sqrt{2} }{5 + \sqrt{2} }$

$\\ \sf = \frac{(5 + \sqrt{2}) }{5 - \sqrt{2} } \times \frac{(5 + \sqrt{2}) }{5 + \sqrt{2} }$

$\\ \sf = \frac{25 + 5 \sqrt{2 } + 5 \sqrt{2} + 2 }{( {5})^{2} - ( \sqrt{ {2}})^{2} }$

$\\ \sf = \frac{27 + 10 \sqrt{2} }{25 - 2}$

$\\ \sf = \frac{27 - 10 \sqrt{2} }{23}$

Now putting the value of√2

$\\ \sf = \frac{27 + 10 \times 1.414}{23}$

$\\ \sf = \frac{27 + 14.14}{23}$

$\\ \sf = \frac{41.14}{23}$

$\\ \sf = 1.787$
