I think it would be 18.8 after rounding to the nearest tenth as long as the radius is 3cm
(2x)/3 = 4
first multiply both sides by 3 to clear the fraction
2x = 12
next divide both sides by 2
x = 6
Function represents a relationship between variables. The product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.
<h3>What is Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given to us
k(x) = 2x² − 7
p(x) = x − 4
As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,

therefore,

Hence, the product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.
