Question

If the radius of the sector is 4 and the length of its corresponding arc is 14, then the area of the sector is:​

Answer 1

Answer:

ANSWER

We have,

Radius of circle=14cm.

Length of arc=22cm.

Using formula,

Angle=arcradius

Now,

Angle=1422

Angle=2×722

Angle=2π(π=722)

Angle=θ=2π

So,

Area of sector =360oθ×πr2

=360o90o×722×14×14

=41×22×2×14

=22×7

=154sq.cm.

Hence, this is the answers
