if in each 15 questions he solve 4 so by dividing 60 by 15 we get 4 . so we multiply 4 by 4 and we get 16
Hey there! :)
Answer:
r ≈ 4.38 cm.
Step-by-step explanation:
Find the radius by working backwards using the equation A = πr²:
Given:
A = 60.24 cm²
π = 3.14
Plug these into the equation:
60.24 = 3.14r²
Divide both sides by 3.14:
19.185 = r²
Take the square root of both sides:
r ≈ 4.38 cm.
