Answer:
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ is the central angle formed at the center of the circle.
r represents the radius of the circle.
π represents a constant whose value is 3.14
From the information given,
r = 21 inches
θ = 25 degrees
Length of arc formed = 25/360 × 2 × 3.14 × 21 = 9.2 inches,

Answer:
THEN ITS POSITION FROM SEA LEVEL=80-25
=55
£1 = 100p
£2 = 2 · 100p = 200p
20p = 20/200 = 1/10
