The answer for number 17

Mathematics
1 answer:
Sedbober [7]4 years ago
4 0
Since cube has all faces as Squares

perimeter of each face P = 22.2
as we know perimeter of a square is P = 4 * ( Sides of a square )

let the sides of the square be 'x'

Hence , 22.2 = 4 * x

=> x = 22.2/4
=> x = 5.55

hence the edge's length is 5.55

Note : if the length from edge to edge is asked then

Length of the Diagonal for a cube =
\sqrt{3}  \times x
Hence we get edge to edge length as

√3 * 5.55 = 9.612

Volume problem.... Please help
vladimir1956 [14]

Answer:

c

Step-by-step explanation:

volume of cylinder = πr^2h

r = 6.5

h = 13+13+13 = 39

cylinder volume = 1647.75π cm^3

volume of one sphere = 4/3 π r^3

= 366.16π cm^3

space not occupied by tennis balls = 1647.75π-3(366.16π)=549.25π cm^3
