use the pythagoream theorem to check. a^2+b^2=c^2

a=15 b=36 c= 39

225+1296=1521

The equation is true so it is a right triangle.

Answer:

59)

Therefore the height of the pyramid is 14 meter.

60)

Therefore the Diameter of Cone is 17.32 cm.

Step-by-step explanation:

59 )

Given:

Shape is Rectangular Pyramid,

Length = 3 meter

Width = 8 meter

Volume of Rectangular Pyramid = 112 cubic meter

To Find:

Height:

Solution:

We Know,

\textrm{Volume of Rectangular Pyramid}=\frac{1}{3}(Length\times Width\times Height)

Substituting the given values we have

112=\frac{1}{3}(3\times 8\times Height)\\ \\\therefore Height=\frac{336}{24}\\\\\therefore Height=14\ meter\\

Therefore the height of the pyramid is 14 meter.

60 )

Thee shape is of Cone

Given:

Height= 5 cm

Volume of cone = 125 π cm³

To Find:

Diameter of a cone = d = ?

Solution:

We know,

\textrm{Volume of cone}=\frac{1}{12}\pi (Diameter) ^{2}\times Height

Substituting the given values we have

125\pi =\frac{1}{12}\pi  d^{2}\times 5\\ \\d^{2}=25\times 12\\  \\d^{2}=300\\\\d=17.32\\   \therefore Diameter = 17.32\ cm

Therefore the Diameter of Cone is 17.32 cm.

Alborosie

Answer:

22%     0.3      19/50

Because 22%

0.3=30%

19 out of 50 percentage would be a 38%


So first is 22% then since 0.3=30% it's next andthen 19 out of 50 since that= 38% And then there you go.
