Given:

The diameter of a sphere is 19 cm.

To find:

The volume of the sphere.

Solution:

We have,

Diameter=19\text{ cm}

Radius=\dfrac{19}{2}\text{ cm}

The volume of the sphere is

V=\dfrac{4}{3}\pi r^2

where, r is radius.

Putting \pi=\dfrac{22}{7}, r=\dfrac{19}{2} in the above formula.

V=\dfrac{4}{3}\times \dfrac{22}{7}\times (\dfrac{19}{2})^3

V=\dfrac{4}{3}\times \dfrac{22}{7}\times \dfrac{19}{2}\times \dfrac{19}{2}\times \dfrac{19}{2}

V=\dfrac{75449}{21}

V=3592.80952

V\approx 3592.8

Therefore, the volume of the sphere is 3592.8 sq. cm.

Find the x and the area of the shape perimeter is 64.5​
Umnica [9.8K]

Answer:

x=8

A = 192

Step-by-step explanation:

The perimeter is the sum of the outer lengths

17.9 + 22.6 + 3x = 64.5

Combine like terms

40.5 +3x = 64.5

Subtract 40.5 from each side

40.5 +3x -40.5 = 64.5 - 40.5

3x =24

Divide each side by 3

3x/3 = 24/3

x = 8

The area of a triangle is given by

A = 1/2 bh

The base is 3x = 3(8) =24

and the height is 2x = 2(8) =16

A = 1/2 (24) * 16

A =192
