If the surface area of the cylinder is 12π square meters. Then the radius of the sphere will be 1.7 meters.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
A cylinder has a height of 4 meters and a radius of 1.5 meters.
Then the approximate radius of a sphere that has the same surface area as the cylinder.
We know that the Surface area of the cylinder will be is given as
Surface area = 2πrh
Surface area = 2 x π x 1.5 x 4
Surface area = 12π square meters
Then we have
Surface area of sphere = surface area of cylinder
4πr² = 12π
r² = 3
r = 1.7 meters

Answer:
2,3,4,5,13,20,25 or
2,4,16,20(even number)
3,5,13,25 (odd number)
Step-by-step explanation:
Answer:
x= -3 or 4/3
Step-by-step explanation:
3x²+5x-12 =0
3x²+9x-4x-12=0
3x(x+3) -4(x+3) =0
(3x-4)(x+3)=0
x=-3 or 4/3
Marco needs to save a minimum of $420 more to buy a smartphone.
<u>Explanation:</u>
Cost of a smartphone = $495
Savings = $75
Least amount of money, m that needs to be saved = ?
Additional savings, m = Total - initial savings
m = $495 - $75
m = $420
The inequality equation would be 75 + m ≥ 495
Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.
