Answer:
The diameter of the circle = 10 cm
The radius of the circle= 10/2= 5 cm
Step-by-step explanation:
Area of the circle = pi r^2
= pi 5^2
=3.14 *25
= 78.5 cm ^2
X=4.1
.,/.,/.,/.,./,/.,./,./,/.,/.,/.,/.,.,/<>,/><>?<?><?,>?<?></.,?>,?><?,?>,?><.?><
As x approaches 5
hmm, we can divide the (x-5) from top and bottom to get x-5
if we input 5 for x we get
5-5=0
it approaches 0 as x approaches 5
