Question

The perimeter of the cardioid r = a (1 + cos @) is
O a
O 2a
o 4a
C 8a​

Answer 1

Answer:

C=8a

Step-by-step explanation:

Complete step-by-step solution: In this question, we are supposed to find the entire length of the cardioid r=a(1+cosθ). So, before proceeding for this, we must know that the cardioids is symmetrical about the initial line, and for its upper half, θ goes on increasing from 0 to π. So, the length of the cardioids is 8a.
