Answer:
find the diameter and area of a circle whose circumference is 220 CM
Step-by-step explanation:
find the diameter and area of a circle whose circumference is 220 CM
Step-by-step explanation:
let diameter be x
Circumference of Circle = π×D
= 22÷7×x = 220
= 22x = 220×7
= 22x = 1540
= x = 1540/22
= x = 70
Diameter of circle is 70cm
Radius of circle = 70÷2 = 35
Area of circle = π×r²
= 22÷7×35²
= 3850
Area of circle is 3850cm
