a .
What is the length of the petals of this rose?
Enter your answer in the box.

Answer 1

The length of the petals of this rose is 7 (units)

Explanation:

The polar equation of a rose curve is either
`r=a\cos n\theta` or
`r=a \sin n\theta`. The number of rose petals will be n or 2n according as n is an odd or an even integer, while the value of
`a` determines the length of a rose petal. Thus, the length of each petal is 7 as
`a=7`.
