Answer:
yes
Step-by-step explanation:
because area of sphere equals =

so if we doubled the radius the surface area will be doubled
x would equal 24
24/2 - 24/3 = 4
Answer:
V ≈ 2011 cm³
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × perpendicular height
V = πr²h ( r is the radius and h the height )
Here r = 8 and h = 10, thus
V = π × 8² × 10
= π × 64 × 10 = 640π ≈ 2011 cm³ ( to nearest whole number )
