In circle O, tangent PN and secant PMQ are drawn to the circle from exterior point P. If PM= 8 and MQ=7 then which of the following is the length of PN? (1) 2square root 14

(2) square root 105

(3) 2 square root 30

(4) 7.5

step-by-step explanation:

it me < 3

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
