The diameter of a soccer ball is 8.65 inches what is the volume of the ball rounded to nearest hundredth

Answers

Answer 1

Answer: A soccer ball is an icosahedron with curved faces that is why it can be regarded as spherical. The volume of a sphere is calculated through,

Vs = 4πr^3/3

where Vs is the volume and r is radius. From the given, 8.65 in is the diameter which is 4.325 in in radius.

Vs = 4π(4.325^3)/3 = 338.88 in cubed.

Thus, the volume of the ball is 338. 88 in cubed.

A+2=e b-2=e c×2=e d:2=e divide 45 in 4 parts example (20,15,3,7) equation will be correct as abcd

Answers

a+2=e
b-2=e

2c=e

d/2=e
dunno wat last part is but since they all equal e
a+2=b-2=2c=d/2
I am guessing that a+b+c+d=45 such that a+2=b-2=2c=d/2

interesting
make in terms of one thing
let's do a

a+2=b-2
a+4=b

a+2=2c
(a+2)/2=c

a+2=d/2
2(a+2)=d

sub

a+(a+4)+[(a+2)/2]+(2(a+2))=45
distribute some
a+a+4+(a+2)/2+2a+4=45
add like terms
4a+8+(a+2)/2=45
minus 8
4a+(a+2)/2=37
mult both sides by 2
8a+a+2=74
add like terms
9a+2=74
minus 2
9a=72
divide 9
a=8

sub back

a+4=b, 8+4=b=12

(a+2)/2=c, (8+2)/2=10/2=c=5

2(a+2)=d, 2(8+2)=2(10)=d=20

a=8
b=12
c=5
d=20
