Formula Formula A polynomial with degree 2 is called a quadratic polynomial. A quadratic equation can be simplified to the standard form: ax² + bx + c = 0 Where, a ≠ 0. A, b, c are coefficients. c is also called "constant". 'x' is the unknown quantity
Expert Solution & Answer
To determine
To find the radius of a circle.
Answer to Problem 23P
The radius of circle is 5.64 in .
Explanation of Solution
Given:
The area of circle is 100 in2
Calculation:
Let the radius of circle be x
So, the area of circle is equals to πx2
also it is given that area of circle is 100 in2
Area=πx2πx2=100x2=31.83Taking square root both sidex=31.83=5.64
