If the sphere shown above has a radius of 11 units then what is the approximate volume of the sphere

adell [148]

Answer:

Volume of the sphere $=5563.58units^3$

Step-by-step explanation:

Volume of the sphere= $\frac{4}{3} *\pi *r^3$

The sphere has given radius(r)= 11 units

Putting the value of the radius in the formula;

Volume of the sphere:

= $\frac{4}{3} *3.14*11*11*11$

$=1.33*3.14*11*11*11$

$=4.18*11*11*11$

$=4.18*1331$

Volume $=5563.58units^3$

The volume of the sphere with radius of 11 units is $5563.58units^3$

sergeinik [125]

Step-by-step explanation:

perimeter=28

length=2x

width=x

28=2(x+2x)

28=2x+4x

28=6x

28/6=6x/6

4.67=x

width=4.67

length=2×4.67
