Answer:
4
Step-by-step explanation:
if 36.24 is divided by 90.6 can be 9.06
36.24÷9.06
4
or by other style
36.24×100=3624
90.6×100= 9060
according to the question
36.24÷90.6 or 3624÷9060
=4 or 0.4
Solution:
Given:

when a = 4, substitute for a in the expression;

Therefore, if (a = 4), then

Hence, the answer is 16.
The Interest Rate, The Time And The Principle Amount
First we need to find the radius. Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:
r=((5-1)^2+(2-2)^2)^(1/2)
r=(4^2-0^2)^(1/2)
r=4 units.
Circumference=2pr so our circumference is 8p units^2
Approximately 25.13 u^2
