Head (Sphere) radius =5
Surface Area:
Volume:
it is the sphere
Surface area of a sphere = 4 pi r^2
Volume of a sphere = 4/3 pi r^3 r = 5 in in this case......I'll let you plug and chug
im ssorry, i dont get it TOT
Here's what EP is saying
Volume = (4/3)pi (radius)^3 = (4/3)pi (5)^3 = (4/3)pi* 125 ≈ 523.6 units^3
Surface Area = 4pi (radius)^2 = 4pi (5)^2 = 100pi ≈ 314.16 units^2
The surface area of the sphere is:
\(4\pi r^{ 2 }=4\pi \times 5^{ 2 }\approx 314.16\)
The volume of the sphere is:
\(\frac { 4 }{ 3 } \pi r^{ 3 }=\frac { 4 }{ 3 } \pi \times 5^{ 3 }\approx 523.6\)
