Answer: Circle
Step-by-step explanation:
Answer:
Radius of the circle is <em>15 inches.</em>
<em></em>
Step-by-step explanation:
Relation between length of arc, radius and the angle subtended by the arc on center is:

where
is the central angle in radians subtended by arc
is the length of arc
is the radius of arc
We are Given the following details:


We know that 
Converting
to radians:
radians
Putting the values of
and
to find the value of 

Hence, Radius of the circle is <em>15 inches.</em>
Answer:
-1
Step-by-step explanation:
If you add 4 to both sides you get
x-4+4=-5+4
the -4and+4 cancel out so you get
x=-1
Answer:
1) Bigger sector = 168.8pi
1) Smaller sector = 56.3pi
2) Bigger sector = 529.9
3) Smaller sector = 176.6
Step-by-step explanation:
1) Bigger sector =
×pi×15×15
= 168.75pi
1) Smaller sector =
×pi×15×15
=
×pi×15×15
= 56.25pi
2) Bigger sector =
×3.14×15×15
= 529.875
2) Smaller sector =
×3.14×15×15
=
×3.14×15×15
= 176.625
