Answer:
Approx = Area = 200.96in^2 when using 3.14 for approx.
A = 201.16in ^2 for calculator.
Step-by-step explanation:
A=πr2
A=3.14 x 8^2 = 64π
A = 201.16in ^2 when using true decimals of pi on calculator
A = 200.96in ^2 Approx 3.14 calculation.
So it is important to actually remember pi as equal to 3.14159 for preciseness.
and not 3.14,

Answer:
B) (4, 0)
C) (0, -1)
E) (2, 3)
Step-by-step explanation:
If we see the rule of function then it says that,
a function is a special relationship where each input, x, has a single output, y.
It means that for every value of x there SHOULD be a different value of y.
A)
(-3,-2) Rejected
because when x = 3, y = -2
D)
(1, 6) Rejected
because when x = 0, y = 6
F)
(-5, 9) Rejected
because when x = 4, y = 9
Surface area of a cube = 486 square inches
Solution:
Given each side of a cube = 9 inches
Net of a cube has 6 squares.
Area of square = side × side
Area of 1 square = 9 × 9 = 81 square inches
Surface area of a cube = Area of 6 squares
= 6 × (side × side)
= 6 × 81
= 486 square inches
Hence, surface area of a cube is 486 square inches.
