Answer:

15.7 cm

Step-by-step explanation:

Angle AD = 180°- 66.4°= 113.6° (considering 2x90°=180° on opposite side)

P= 2*3.14*7.9=49.6 cm

Arc AD= 49.6*113.6°/360°= 15.7 cm

D= kA [T2 - T1 / L] Solve for T1

$d=\dfrac{k_A(T_2-T_1)}{T}\ \ \ \ |multiply\ both\ sides\ by\ T\\\\k_A(T_2-T_1)=dT\ \ \ \ |divide\ both\ sides\ by\ k_A\\\\T_2-T_1=\dfrac{dT}{k_A}\ \ \ \ |subtract\ T_2\ from\ both\ sides\\\\-T_1=\dfrac{dT}{k_A}-T_2\ \ \ \ \ |change\ signs\\\\\boxed{T_1=T_2-\frac{dT}{k_A}}$
