Answer:

As shown in picture, here is a triangular pyramid whose volume is calculated by:

V = (1/3) x base area x height

= (1/3) x 20 x 30 x (1/2) x 27

= (20 x 30 x 27)/(2 x 3)

Hope this helps!

State the radius of this circle:<br> X^2 +Y^2=121

Snowcat [4.5K]

Answer:

radius = 11

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

x² + y² = 121 ← is the equation of a circle centred at the origin

with r² = 121 , then

r = $\sqrt{121}$ = 11
