Answer:
Step-by-step explanation:
Diameter = 28 cm
therefore, radius = 28 / 2 = 14 cm
Circumference = 2 π r
= 2 × 22 / 7 × 14
= <u><em>88 cm</em></u>

First, we have
s1/r1 = s2/r2
The question also states the fact that
s/2πr = θ/360°
Rearranging the second equation, we have
s/r = 2πθ/360°
Then we substitute it to the first equation
s1/r1 = 2πθ1/360°
s2/r2 = 2πθ2/360°
which is now
2πθ1/360° = 2πθ2/360°
By equating both sides, 2π and 360° will be cancelled, therefore leaving
θ1 = θ2
