Basketball

Radius: 12.2 cm
Find the surface area to calculate material needed

r = 12.2 cm

Surface Area of a Sphere Formula

SA = 4πr²

Where π ≈ 3.14159 and r is the radius

Calculate the surface area of this basketball

SA = 4π × r²

SA = 4π × (12.2)²

SA = ?

Surface Area in: cm²

🌐 Surface Area Formula:

• SA = 4πr² (4 × π × radius²)

• π ≈ 3.14159 (pi constant)

• Square the radius first, then multiply by 4π

• Answer will be in square units (cm², m², etc.)

🎮 Real-Life Applications:

• Calculate material needed for balls/spheres

• Find paint coverage for spherical objects

• Determine surface area for scientific calculations

• Use hints for step-by-step solutions

Hongera! Perfect!
