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 the largest circular bed covered by the mulch.
Answer to Problem 26P
The radius of the largest circular bed is 2.9m .
Explanation of Solution
Given information:
The area of the circular bed is 85m2 .
Let r be the radius of the circular bed.
The area of the circular bed is given by πr2
Then,
πr2=85r2=85πr=85πr≈2.9
Therefore, the radius of the largest circular bed is 2.9m .
