<h2>15448 cm³</h2>
Step-by-step explanation:
Volume of a sphere is

where r is the radius
From the question in order to find the volume of the sphere we must first find the radius of the sphere using it's surface area
Surface area of sphere = 4πr²
3000 = 4πr²
Divide both sides by 4π
r² = 750/π
r = 15. 45 cm
Now the volume of the sphere is

<h2>

</h2>
<h3>= 15448 cm³ to the nearest whole number</h3>

Answer:
A = pi*(8 mm)^2 = 64*pi mm^2
Step-by-step explanation:
The formula for the area of a circle is A = pi*r^2, where r is the radius. Thus, r^2 = (25pi) / pi, or 25, and r = 5 mm.
If we increase this radius by 3 mm, we get the new radius 8 mm. The area of the new circle will thus be A = pi*r^2, or, in this particular case,
A = pi*(8 mm)^2 = 64*pi mm^2.
