Question

An umbrella has 8 ribs which are equally spaced. Assuming the umbrella to be falt can circle with radius 56 cm, the area between two consecutive ribs is _____ cm square.​

Answer 1

Answer:

The area between the ribs is 7 cm square

Answer 2

Answer:

☞795.5 cm2

Step-by-step explanation:

☞The radius (r) of the umbrella when flat = 45 cm

☞So, the area of the circle (A) = πr2 = (22/7)×(45)2 =6364.29 cm2

☞Total number of ribs (n) = 8

∴ The area between the two consecutive ribs of the umbrella = A/n

☞6364.29/8 cm2

Or, The area between the two consecutive ribs of the umbrella = 795.5 cm2

☞✓795.5 cm2
