Name the property of real numbers illustrated by the equation. π + 10 = 10 + π

Commutative property of addition

Step-by-step explanation:

It does not matter that which number should be written first or second, i.e if you change the order of addends, the result remains the same.

for any a and b arbitrary real numbers.

The given equation : π + 10 = 10 + π

Here the expressions on each side are same , just the order gets changed.

So the the property of real numbers illustrated by the equation is  commutative property of addition .

your answer is d 2,500

step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
