Answer:

see explanation

Step-by-step explanation:

A

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 12 , then radius = 12 ÷ 2 = 6 , then

A = π × 6² = 3.14 × 36 = 113.04 m²

B

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius )

Here C = 28.26 , then

2πr = 28.26 ( divide both sides by 2π )

r = \frac{28.26}{2(3.14)} = \frac{28.26}{6.28} = 4.5 in

a digital scale measures weight to the nearest 0.2 pound. which measurement shows an appropriate level of precison for the scale
nadezda [96]

Answer:

130.4 pounds

Step-by-step explanation:

The digital scale is measuring weight to the nearest 0.2 pounds, so basically the digital scale would show you the weight of an object that is a multiple of 0.2.

Talking about precision, precision tells us how accurate is the measured value or how close is the measured value to the actual value.

Here, scale is measuring to the nearest 0.2 pounds, so out of the given values the measurement that shows an appropriate level of precision for the scale is 130.4 pounds.

Proofs are used to show that a mathematical statement is true. The most common form of mathematical statements are if-then state
iragen [17]

Answer:

True mathematical statement.

"If x = 0, then for any real number y, we have: y*x = 0."

This is true, and we can prove it with the axioms of the real set.

A false mathematical statement can be:

"if n and x are integer numbers, then n/x is also an integer number."

And a counterexample of this is if we took n = 1 and x = 2, both are integer numbers, so the first part is true, but:

n/x = 1/2 = 0.5 is not an integer number, then the statement is false,
