Hello There!
First thing we want to do is find the formula for circumference of a circle
C = 2(3.14)r
where r = radius
we are given the diameter so we have to convert that into radius to do so we just divide by 2
42/2=21 so the radius equals 21 inches
now we just plug in 21 for r in the formula
So we can conclude that the circumference of the circle is 131.88 inches
Answer:
Domain and Range. The domain of a function is the set of values that we are allowed to plug into our function. This set is the values in a function such as ). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an value in.

Answer: 80
Step-by-step explanation:
-3 = -19 + d/5
-15 = -95 + d
-d-15= -95
-d= -95 + 15
-d = -80
d = 80
The expression 6×9.82 is the result of a product that has the best estimate of 60 option (E) is correct.
<h3>What is an arithmetic operation?</h3>
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have value of quantity is 60
A) 0.63×104 = 65.52
B) 32.4×21 = 68.04
C) 1.1 × 58 = 63.8
D) 0.18×27 = 4.86
E) 6×9.82 = 58.92
The value of 6×9.82 is 58.92 which is best estimate of 60.
Thus, the expression 6×9.82 is the result of a product that has the best estimate of 60 option (E) is correct.

The formula for a circumference of a circle is: C=2π<span>r
and we are given the answer as
C=16</span><span>π
Therefore we know that 16 is from the combination of multiplying 2 and r
So to find r we do the opposite of what is done. The opposite of multiplying is dividing, therefore:
16/2=8
therefore r = 8
The formula for the area of a circle is: </span>A=πr^<span>2
Since we know r = 8 we just sub it into the equation
A=</span><span>π*8^2
A=64</span><span>π or (assuming you want π to two decimal places: 3.14 then) 200.96</span>
