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
