find the area of each shape correct to 1 d.p.(use 3.14 for pi)
Answers
Answer:
Step-by-step explanation:
- Area of the shape01 = area of rectangle + area of the semi-circle
= L * B + ( π r²) / 2
= 4 * 3 + ( 3.14 * 2²) / 2
= 12 + ( 3.14 * 4) / 2
= 12 + 6.3
Area of the shape01 = 18.3 cm²
2. Area of the shape02
= area of rectangle + area of the semi-circle01 + area of semi-circle02
= L * B + ( π r²) / 2 + ( π r²) / 2
= 4 * 3 + ( 3.14 * 2²) / 2 + ( 3.14 * 1²) / 2
= 12 + 6.3 + 1.6
= 19.9 cm²
Area of the shape02= 19.9 cm²
