Given a sphere with a diameter of 6 cm, find its volume to the nearest whole number.

mezya [45]

Answer:

Volume of the sphere is $1.13\times 10^{-4}m^3$

Step-by-step explanation:

It is given diameter of the sphere d = 6 cm = 0.06 m

Radius of the sphere

$r=\frac{d}{2}=\frac{0.06}{2}=0.03m$

We know that volume of the sphere is given by

$V=\frac{4}{3}\pi r^3$

Therefore ,

$V=\frac{4}{3}\times 3.14\times 0.03^3$

$=1.13\times 10^{-4}m^3$

Therefore volume of the sphere is $1.13\times 10^{-4}m^3$

Answer:

Please read all of this! Underlined things are the answers. The area of the entire circle is 19.625

Step-by-step explanation:

(This is a circle so the middle line is the diameter. According to the attachment, the diameter is 5 cm. To find the area, we have to multiply π and the radius squared. The radius is half of the diameter.

5 ÷ 2 = 2.5

2.5² = 6.25

π = 3.14

3.14 x 6.25 = 19.625)

Ignore the top I just realized what I'm supposed to do but I left it there just in case you need help!

The right and left shaded regions areas are 6.28 each.

4 ÷ 2 = 2

2² = 4

3.14 x 4 = 12.56

Since this is a semi circle, we cut it in half.

12.56 ÷ 2 = 6.28

To find the top and bottom shaded region's areas, repeat the same steps.

3 ÷ 2 = 1.5

1.5² = 2.25

3.14 x 2.25 = 7.065

7.065 ÷ 2 = 3.5325

The areas of the the top and bottom shaded regions are 3.5325 each.
