Answer» Answer: Step-by-step explanation: here's your answer: GIVEN: CIRCUMFERENCE = 220 m To find: Diameter and area Solution: First it is necessary to find radius Circumference = 2πr 220 = 2× 22/7 × r 220 × 7 / 2 × 22 = r 5 × 7 = r ( After cancellation) 35 = r Therefore r is 35 m Diameter = 2r = 2 × r =2 × 35 = 70 Therefore Diameter is 70 m Area = πr^2 = 22/7 × 35 × 35 = 22 × 5 × 35 = 3850 m^2 Hope this helps ☺️

Answer»

Answer:

Step-by-step explanation:

here's your answer:

To find:

Diameter and area

Solution:

First it is necessary to find radius

Circumference = 2πr

220 = 2× 22/7 × r

220 × 7 / 2 × 22 = r

5 × 7 = r ( After cancellation)

35 = r

Therefore r is 35 m

Diameter = 2r

= 2 × r

=2 × 35

= 70

Therefore Diameter is 70 m

Area = πr^2

= 22/7 × 35 × 35

= 22 × 5 × 35

= 3850 m^2

Hope this helps ☺️
