Answer:

the vertices of point R could be (-2,5) or (-2,9)

each point is 7 units away from Q since there are 7 units between P and Q

Find the volume of the cone of with a height of 6cm and a diameter of the base or 6cm

Ainat [17]

Answer:

The volume of cone v= 113.04 cm³.

Step-by-step explanation:

Formula used to find volume of cone is:

$v= \pi * r^2 * \frac{h}{3}$

where r is the radius and h is the height of cone.

In the given question we are given:

height h= 6 cm

diameter d= 6 cm

We know radius r = d/2 = 6/2 = 3 cm

so, volume will be:

$v= \pi * 6^2 * \frac{3}{3}$

$v= \pi * 36$

$v=113.04$

So, the volume of cone v= 113.04 cm³ given height h= 6cm and radius r= 3cm

A Pest control company sprays insecticide around the perimeter of a 180 ft by 180 ft building. If the spray costs $.11 per foot,

andreev551 [17]

P = 4a.....this is the perimeter of a square
P = 4(180)
P = 720 ft

and if the spray cost 0.11 per ft......720 * 0.11 = 79.20 rounded to the nearest dollar is $ 79 <==
