If the area of a circle is found using a=πr2, find r if the area is 25in2 and using pi equals 3.14

r = 2.8 in ( to 1 dec. place )

Step-by-step explanation:

substitute the given values into the formula

25 = 3.14r² ( divide both sides by 3.14 )

r² = ( take the square root of both sides )

r = ≈ 2.8 in

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
