4z+6.1≥43.7-4z
add 4z on both sides - 8z+6.1≥43.7
subtract 6.1 on both sides - 8z≥37.6
divide by 8 on both sides - v≥4.7
The answer for the first one is city c
The Volume of the sphere with radius 3 cm is 113.10 cm³ and the surface area is 113.10 cm² .
In the question ,
it is given that ,
the radius of the sphere is = 3 cm
we know that formula for Volume of sphere is
Volume = (4/3)πr³
So , Volume for radius = 3 cm is
Volume = (4/3)π(3)³
= (4/3)*3.14*27
= 113.097
≈ 113.10 cm³
And the formula for the Surface area is given as
Surface Area = 4πr²
Surface area for radius = 3 cm is
Surface Area = 4*3.14*9
= 113.097
≈ 113.10 cm²
Therefore , The Volume of the sphere with radius 3 cm is 113.10 cm³ and the surface area is 113.10 cm² .

Answer:
y = 40
Step-by-step explanation:
y/8 = 5
———————————————————
Multiply both sides by 8:
8y/8 = 5 * 8
———————————————————
Simplify:
y = 40
