Answer:
Step-by-step explanation:
The formula for determining the surface area of a sphere is expressed as
Surface area = 4πr^2
Where
r represents the radius of the sphere
π is a constant whose value is 3.14
From the information given,
Surface area of the sphere = 100 centimeters ^2. Therefore,
100 = 4 × 3.14 × r^2
100 = 12.65r^2
r^2 = 100/12.65 = 7.9051
r = √7.9051
r = 2.81 centimeters
Answer:
15+ (B x 7)
Step-by-step explanation:
125 ÷ 7.75 = 16.13
