Answer:
It is 65.97cm^2
So I think it is option B) 21 pi = 65.97
V=pi(3^2)7/3
Step-by-step explanation:
The circumference of a circle with an area of 50.3 m² is 25.12 m.
<h2>Further Explanation </h2><h3>Area </h3>
- Area is a measure of how much space is occupied by a given shape.
- Area of a substance is determined by the type of shape in question.
For example;
- Area of a rectangle is given by; Length multiplied by width
- Area of a triangle = 1/2 x base x height
- Area of a circle = πr². where r is the radius of a circle,
- Area of a square = S², Where s is the side of the square.etc.
<h3>Perimeter </h3>
- Perimeter is defined as the distance along a two dimension shape. Perimeter of different shapes is given by different formulas
For example;
- The perimeter of a rectangle = 2(length+width)
- The perimeter of a triangle = a+b+c; where a, b and c are the sides of the triangle. etc.
- The Circumference of a circle = 2πr , where r is the radius of the circle
In this case;
The Area of a circle = 50.3 m²
π = 3.14
But; Area of a circle = πr²
Therefore;
3.14r²= 50.3 m²
r² = 50.3/3.14
=16.019
r = √16.019
= 4.0023
≈ 4.00
But;
Circumference of a circle is given by 2πr
Thus;
Circumference = 2 × 3.14 × 4.00
= 25.12 m

Step-by-step explanation:
<u>Note</u>:
<u>Slope intercept form</u>: y = mx + b
<u>Standard slope form</u>: Ax + By = C
<u>Point slope form</u>: (y-y1) = m(x - x1)
m = slope.
10.
Form: Slope intercept form
Slope: 6/7
y-intercept = 1
11.
Form: Point slope form
Slope = 9
y -intercept = -13
y - 5 = 9 (x-2)
y - 5 = 9x - 18
y = 9x - 18 + 5
y = 9x - 13
12.
Form: Standard slope form
25. Sarah is correct, Katie is incorrect. Both graph have right slope -2/5, but Katie has incorrect y-intercept.
