Answer:
if 3 in is the radius the area is 113.1
if 3 is the diameter the area is 28.27
Step-by-step explanation:
A=4•π•r squared
Answer:
gavin gets £51
sarah gets £34
pip gets £51
Step-by-step explanation:
3 + 2 + 3 = 8
136 ÷ 8 = 17, so 1 = 17
gavin = 3 x 17 (51)
sarah = 2 x 17 ( 34)
pip = 3x17 (51)
51+51+34= 136
The answer is 4. you distribute the negative to make a positive sign and then add
Answer:
Step-by-step explanation:
The formula for determining the volume of a sphere is expressed as
Volume = (4/3) × πr³
The volume of the given sphere is expressed as 288π inches³. It means that
(4/3) × πr³ = 288π
4r³/3 = 288
4r³ = 3 × 288 = 864
r³ = 864/4 = 216
Taking cube root of both sides, it becomes
r = 6
The formula for determining the surface area of a sphere is expressed as
Area = 4πr²
π = 3.14
Therefore,
Surface area = 4 × 3.14 × 6² = 452.16 inches²
