Answer 1

Answer:

ANSWER: The pool's circumference is 37.7 ft^2 (rounded to nearest tenth).

Step-by-step explanation:

Answer 2

d =8.27 ( approx)

Jada need 47.1 feet of protective material around the rim of the pool.

circumference: In mathematics, the perimeter of any shape defines a path or boundary that surrounds the shape. In other words, the perimeter is also called the perimeter, which helps to identify the length of the outline of any shape. As we know, circumference and area of ​​a circle are two important parameters of a circle. In this article we will discuss "Circumference of a Circle" or "Circumference of a Circle" with its definition, formula, methods to find the circumference of a circle with many solved examples.

diameter: In geometry, a circle is a 2D shape where a collection of points on the surface of the circle are equidistant from the center. The distance from the center to any point on the surface is called the radius. Similarly, the distance from one point on the surface of a circle to another point on the surface of the circle passing through the center is called the diameter. In other words, the diameter is twice the radius. We can say that the diameter is the longest chord of a circle. The symbols used to represent diameter are "d", "φ", "D", "Dia".

As per the question we need to find the approximate diameter of a circle.

The given data is circumference of a circle is 26 5/7 ft..

and use 22/7 for π.

Therefore

circumference of the circle is = 26 ft.

we know that

C =2πr

and d =2r.

Therefore d = C/π.

                   = $\frac{26}{\frac{22}{7} }$

              d =8.27 ( approx)

Now the 2nd part of the question

in this part we need to find the how many feet of protective material does jada need.

given that

A circular swimming pool has a diameter of 15 feet.

Formula for area of circle = πr²  where 'r' is the radius of the circle.

                                            = (3.14) (15)  

                                              = 47.1

Hence, Jada need 47.1 feet of protective material around the rim of the pool.
