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
Answer:
276
Step-by-step explanation:

Answer:
that answe is b
Step-by-step explanation:
b because i took this test
Answer: :,)
Step-by-step explanation:
so u see were the b is in the triangle it want u to find how much b is worth
Perimeter = 2L + 2W (where L = length and W = width)
And we are given that L = 3W
So substituting for L, we have the equation:-
2(3W) + 2W = 64
6W + 2W = 64
8W = 64
W = 8 meters
So the length = 3*8 = 24 meters
Answer:- Length = 24 m and Width = 8 m.
