Answer:
A = 346.185 cm²
Step-by-step explanation:
The formula given is:
A = πr²
A = Area of the object (circle).
π = 3.14
r = radius, which is 1/2 of the diameter, a straight line from one end to the other.
Set the equation, plug in the corresponding numbers to the corresponding variables:
A = (3.14)(10.5)²
Simplify. Remember to follow PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
and is the order of operation.
First, solve the exponent.
(10.5)² = 10.5 * 10.5 = 110.25
Next, multiply:
A = (3.14)(110.25)
A = 346.185 cm²
A = 346.185 cm² is your answer.

Answer:
True.
Step-by-step explanation:
Any number that can be written as a fraction a/b where a and b are integers (neither a nor b= 0) is rational,
For example 3 ( = 3/1) , 1/3 , 5/10 are all rational.

Answer:
x = -7
Step-by-step explanation:
Substitute the given value and solve for x
n(x) = -6x +2
44 = -6x + 2
42 = -6x . . . . . subtract 2
-7 = x . . . . . . . divide by -7
n(x) will have the value 44 for x = -7.
