The arc made by a sector at center is 72 degrees . Given that the length of an arc is 44cm ,calculate the radius of the circle (
lesantik [10]

Given:

Central angle of a sector = 72 degrees

Intercepted arc length = 44 cm

To find:

The radius of the circle.

Solution:

We know that, the arc length is

s=2pi r\dfrac{\theta }{360^\circ}

Where, r is the radius of the circle, \theta is the central angle in degrees.

Putting s=44,\pi=3.14 and \theta = 72^\circ, we get

44=2(3.14)r\dfrac{72^\circ }{360^\circ}

44=6.28r(0.2)

44=1.256r

Divide both sides by 1.256.

\dfrac{44}{1.256}=r

35.031847=r

r=35.03

Therefore, the radius of the circle is about 35.03 cm.

egoroff_w [7]

Answer:

10,935 bunnies at the end of 7 weeks  

Step-by-step explanation:

5 x 3 = 15

            ^  x 3 = 45

                          ^ x 3 = 135

                                        ^  x 3 = 405

                                                        ^  x 3 = 1,215

                                                                         ^ x 3 = 3,645

                                                                                         ^ x 3 = 10,935

I may be <u><em>way </em></u>off, forgive me, but I hope this helps anyway, have a good day!!

A cuboid, with dimensions 28cm by 16cm by 15cm, has a volume of 6720cm cube. The cuboid is melted to form smaller cubes of lengt
Dovator [93]

Answer:

Vol of the cube =Vol of cubiod

Vol of each smaller cube =s×s×s= 4×4×4=64

Vol of cuboid /Vol of each smaller cube = no of cubes that can be obtained

6720/64= 105

Hence 105 cubes can be obtained
