Answer:
The equation shows the commutative property of addition is 4 +3 = 3 + 4 .
Option (A) is correct.
Step-by-step explanation:
Commutative property of addition
The commutative property for addition states that
a + b = b + a .
Where a, b are any number.
thus
this above condition is satisfied by equation
4 + 3 = 3 + 4
7 = 7
Therefore Option (A) is correct.
Answer:
63.59 in²
Step-by-step explanation:
The formula to find the area of a square: a², where a is the side.
The formula to find the area of a circle: πr², where r is the radius (diameter ÷ 2), and the pi is alterable (3.14 or 3.142 or 22/7).
1) Find the diameter of the circle. The side of a square is the diameter.
a²
a = √81
a = 9
2) Plug the values into the formula of the area of a circle. 9 ÷ 2 = 4.5 (radius).
= 3.14 x 4.5²
= 3.14 x 20.25
= 63.585
3) Round off the result to the nearest hundredth.
= 63.59
