A circle has a radias of 12in. The diameter of the circle is _____in. In order to find the area of the circle, use the formula ____ The area of the circle is ____Thanks

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

The diameter of the circle is twice the radius, so the diameter of the circle is 2 x 12 inches = 24 inches.

To find the area of the circle, we can use the formula A = πr^2, where A is the area of the circle and r is the radius.

So, for this circle, A = π(12 inches)^2 = 144π square inches.

Therefore, the diameter of the circle is 24 inches, the formula to find the area of the circle is A = πr^2, and the area of the circle is 144π square inches.
Answer 2
Answer:

Answer: 144 pie square inches!

Step-by-step explanation:

1st blank : is 24 square inches since the radius which is half the diameter is 12 square inches we can easily know that the diameter would be 24 square inches!

2nd blank : pie r squared is the formula! for all areas of the circles! the total length in other words the circumference of the circle would be 2 pie r basically multiplying 2 and pie and the radius.

3rd blank : the area of the circle is 144 pie (square inches)!

The inscribed angle theorem says that the angle formed by two intersecting chords of a circle (the angle A between the chords AC and AB in this case) has half the measure of the central angle subtended by the arc containing those chords (arc CB in this case). So

m\angle BAC=\frac12m\angle BFC\implies m\angle BFC=2\cdot35^\circ=70^\circ

At its highest​ point, the elevation of a county is 5,776 feet above sea level. At its lowest​ point, the elevation of the county is 6 feet below sea level. Write an expression using integers to represent the difference between the elevations.
(Do not​ simplify.)

The expression that represents the elevation is 5,776-(-9)=5,785.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that at its highest​ point, the elevation of a county is 5,776 feet above sea level. At its lowest​ point, the elevation of the county is 6 feet below sea level.

The expression will be generated by subtracting the two heights.

5,776-(-9) = 5,785.

Therefore, the expression that represents the elevation is 5,776-(-9)=5,785.
