Question

The area (A) of a ring is A = π r2 - π s2. Find the area A if π = 3.14, r = 6 and s = 4.
A = 62.8
A = 197.192
A = 31.4
A = 6.28



Question 6

Answer 1

so let's substitute

A = (3.14)(6)^2 - (3.14)(4)^2

so where are you getting confused?

Answer 2

it's 62.8

Answer 3

i m preety sure on it
