Dear Student,
● Answer -
154 m²
● Explanation -
# Given -
Inner diameter, d = 7 m
# Solution -
Inner radius of hollow sphere is calculated -
r = d/2
r = 7/2 m
Area of sphere available to the motorcyclist for riding is calculated by -
A = 4πr²
A = 4 × 22/7 × (7/2)²
A = 4 × 22/7 × 7 × 7 / 4
A = 22 × 7
A = 154 m²
Therefore, area available to the motorcyclist for riding is 154 m².
