Answer:
1. 200.96 cm²
2. 63 cm²
3. 225 cm²
4. 4 m
5. 113. 04 mm²
Step-by-step explanation:
1. Area of Circle = πr²
A = 3.14 (8)²
A = 3.14 (64)
A = 200.96
The area of the circle is 200.96 cm².
2. Area of Rectangle = lw
A = 9 × 7
A = 63
The area of the front and back faces of the prism is 63 cm².
3. Area of Square = s²
A = 15²
A = 225
The area of the base in square pyramid is 225 cm².
4. Radius = Diameter ÷ 2
r = 8 ÷ 2
r = 4
The radius is 4 m.
5. Area of Circle = πr²
A = 3.14 (6)²
A = 3.14 (36)
A = 113.04
The area of the two bases is 113.04 mm².
