Answer:
1. 64π cm²
2. 63 cm²
3. 225 cm²
4. 4 m
5. 36π cm²
Step-by-step explanation:
1. Formula for Circle Area
A = πr² || Given r = 8
A = π(8)²
A = 64π cm²
2. Formula for Area
A = length x width || Given: l = 7 and w = 9
A = 7 x 9
A = 63 cm² (both front and back)
3. Formula for Area
A = length x width || Given: l = 15 and w = 15
A = 15 x 15
A = 225 cm²
4. Radius is half the diameter || Diameter = 8
8 ÷ 2 = 4 m
5. Formula for the bases of Cylinder
A = πr² || Given r = 6
A = π(6)²
A = 36π cm²
