Question

A circular field has a circular pool inside it.If radius of the field is 20m and that of the pool is 13m.Find the area of the space between the pool and the field ?​

Answer 1

Answer:

first find the area of the big circle ( field) and then find the area of the small circl(pool) then subtract them both.

Step-by-step explanation:

area of circle = πr^2

Answer 2

Step-by-step explanation:

R1 = 20 m

R2 = 13m

area of the space between the pool and the field = area of field - area of pool

πr² = (πr1) ² - (πr2)²

= (3.14 ×20×20). -. (3.14×13×13)

= (3.14×400)-(3.14×169)
