Find the circumference and the area of a circle with radius 7ft .
Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.

Answers

Answer 1

Answer:

C=43.96 ft.

A=153.86 ft.^2

Step-by-step explanation:

for circumference, use C=2πr

for area, use A=π[tex]r^{2}[/tex]

Answer 2

The circumference and the area of a circle with radius 7 feet are 43.96 feet and 153.86 square feet, respectively.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

where (h, k) is the center and r is the radius of the circle.

Given:

A circle with radius 7 feet.

Then the circumference of the circle,

= 2πr

= 2(3.14)(7)

= 43.96 feet.

The area of the circle,

= πr²

= (3.14) (49)

= 153.86 square feet.

Therefore, circumference is 43.96 feet and area is 153.86 square feet.

The coordinate of the z² will be (4, 1) which is represented by point D. Then the correct option is D.

What is coordinate geometry?

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The coordinate of the z will be given from the graph.

The coordinate of z is (2, 1).

If the square is of z is done, then the coordinate of the z² will be

z ⇒ (2, 1)

z² ⇒ (2, 1)²

z² ⇒ (2², 1²)

z² ⇒ (4, 1)

The coordinate of the z² will be (4, 1) which is represented by point D.

Then the correct option is D.
