Given that the arc length is 4.189 cm and the radius is 3 cm, the size of the arc will found as follows;
C=theta/360 πd
suppose:
size of arc=theta=x
d=3*2=6 cm
hence;
4.189=x/360*π*6
4.189=0.0524x
x=4.189/0.0524
x=80.004°
The size of the arc length is 80.004°
The right answer is, 18+14.
Answer:
a 87
b 814
Step-by-step explanation:
It you like my answer than please mark me brainliest thanks
Vanshi and the answe would be 179 and also 190 for b
Wide is diameter
to get radius 1.9/2
then use a calculator with this formula 2(3.14)(1.9/2)
or you can use (3.14)(diameter) the diameter was 1.9
so (3.14)(1.9)
