Answer:
Mark as brainliest answer.
Step-by-step explanation:
→ d = 0.7
→ r= 0.7/2
→ r = 0.35
→ perimeter of semi circle = 2πr/2
→ (2 × 22/7 × 35/100 ) / 2
→ 1540/700/2
→ 3080/700
→ 4.4 cm
→ Area of semi circle = πr²/2
→ (22/7 × 35/100 × 35/100 ) / 2
→ 26950/70000/2
→ 53900/70000
→ 0.77 cm²

Answer:
Perimeter of semicircle = 1.099 cm
Area of semicircle = 0.1225
Step-by-step explanation:
Perimeter of semicircle = 1/2 πd
Diameter = 0.7
Perimeter = 1/2 * 3.14 * 0.7
= 1.099 cm
radius = 0.7/2 = 0.35
Area of semicircle = 1/2 πr square
= 1/2* 3.14 * 0.35 * 0.35
= 0.1225
