Answer:
C
Step-by-step explanation:
The central angle is 20% of 360°, that is
central angle = × 360° = 0.2 × 360° = 72° → C
5.5 • 5= 27.5+27.5+65+65+71.5+71.5=328
13•5=65
13•5.5=71.5
THE ANSWER IS 328
Answer:
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.
