Question

semi-circular part was removed from
rectangular field as shown in
figure. What is new perimeter
of field?​

Answer 1

Answer:

56.5663706144

Step-by-step explanation:

Length of curve of semicircle = $\frac{1}{2}$  × π × 8

                                                 = 4π

New perimeter = 2 × 15 + 11 + (11 - 8) + 4π

                         = 56.5663706144

It depends of how many decimal places/significant fingures your school wants
