Question

Find in degrees the angle subtencled at the
center of the cercle of radius 100cm of an are
length
200 cm.​

Answer 1

Answer:

Step-by-step explanation:

Let the angle be∅

We have given the radius = 100 cm

Also , we have arc's length = 200 cm

Applying the formula ,

                Length of an arc= ∅/360° × 2πr

                                     200= ∅/360° ×2×22/7×100

                                        360×7/22=∅

                                      114.54°=∅
