The area of the base of the oblique pentagonal pyramid is 50 cm2 and the distance from the apex to the center of the pentagon is
kirza4 [7]

Answer:

\text{Height is }6\sqrt2cm

\text{The volume is }100\sqrt2cm^3    

Step-by-step explanation:

Given the area of the base of the oblique pentagonal pyramid is 50 cm^2 and the distance from the apex to the center of the pentagon is 6 cm. The measure of ∠ACB is 45°.

we know that

ABC is a right triangle

∠ACB=45°

AC=hypotenuse------> 6 cm

\sin 45^{\circ}=\frac{AB}{AC}

AB=AC\times \sin 45

AB=\frac{6}{\sqrt2}

AB=3\sqrt2

\text{Height is }6\sqrt2cm

Now, volume of pyramid

\text{Volume of the pyramid=}\frac{1}{3}\times \text{Area of the base}\times height

Area of the base=50 cm²

Height=6\sqrt2 cm

so, \text{volume of the pyramid=}\frac{1}{3}\times 50\times 6\sqrt2=100\sqrt2cm^3

\text{the volume is }100\sqrt2cm^3
