Question

answer the above questions

Answer 1

Answer:

452.57cm^2 (approx)

Step-by-step explanation:

volume of smaller sphere= 4/3(pie)r^3

total volume of cubes = 27*4/3(pie)r^3

total volume of spheres = volume of larger sphere

this gives radius of larger sphere = 6cm

surface area= 4(pie)r^2 = 452.57cm^2 (approx)

Answer 2

$\frac{2200}{7}$
314.28 cm^3
