38.4 I times 12.80 by 3 .
p.s I use a calculator☺
Given:
Area of a sector = 64 m²
The central angle is
.
To find:
The radius or the value of r.
Solution:
Area of a sector is:

Where, r is the radius of the circle and
is the central angle of the sector in radian.
Putting
, we get




Taking square root on both sides, we get


Therefore, the value of r is
m.
Answer:
f(2)=5, f(-2)=-7
Step-by-step explanation:
Step 1 : f(2)=3(x)-1
f(2)=5
Step 2 : f(-2)=3(x)-1
f(-2)=-7
You may represent this multiple ways.
1. 66/44 = m
2. 44m = 66
In both of these scenarios you have a total and equal parts.
The first one starts with a total and breaks it into equal parts.
The second choice shows 44 groups of a part totaling 66 meters.
Answer:
that would be 38 degrees
