Step-by-step explanation:
circumference of circular in black is equal to 2Πr
Therefore,
88 = 2 × 22 ÷ 7 × r
14 = r
area of circular tin plate is Πrr
therefore,
area = 22÷7 × 14 × 14
area = 616 cm squre

Answer:
Area of a circular tin plate is 616 cm²
Step-by-step explanation:
SOLUTION
Given,
The circumference of a circular tin plate is 88 cm.
Find,
It's area.
=> π be 22/7
=> 2πr = 88
=> 2 × 22/7 × r = 88
=> r = 88 × 7/2 × 22
=> r = 14 cm
So,
Area = πr²
Area = (22/7) × 14 × 14
Area = 616 cm²
Hence,
The area of circular tin plate is 616 cm²
