Step-by-step explanation:answer is above in picture

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.
