Ksenya-84 [330]

Answer:

90°

Step-by-step explanation:

since PQ is the diameter of the circle, m <em>L</em><em> </em>PRQ = ½ × 180° = 90°.

so, as a supplementary to <em>L</em><em> </em>PRQ, the value of angle QRS = 180 - m <em>L</em><em> </em>PRQ = 180-90 =90°

A pyramid has a base area of 44cm and a height of 12.6 cm what is the volume of the pyramid ?
aliya0001 [1]

Answer:

184.8 cubic cm

Step-by-step explanation:

The formula for the volume of a pyramid is

V = (1/3)(B)(h)      where B is the area of the base, and h is the height

We are given B = 44 cm² andh = 12.6cm  

Plug them into the formula and simplify...(I'm assuming you are allowed to use a calculator for these problems)

V = (1/3)(44cm²)(12.6cm)

<h2>     V = 184.8 cm³  or 184.8 cubic cm</h2><h2 />
