An upright cylindrical tank with radius 8 m is being filled with water at a rate of 2 m3/min. How fast is the height of the wate

Fiesta28 [93]

Answer:

16 goes in the blank

Step-by-step explanation:

V(c) = 2*π*r*h

Differentiating boh sides

DV(c)/Dt = 2πr Dh/Dt now radius is 8 m

DV(c)/Dt = 8π Dh/Dt

That expression gives the relation of changes in V and h

DV(c)/Dt is the speed of growing of the volume

Dh/Dt is the speed of increase in height

so if the cylinder is filling at a rate of 2 m³/min the height will increase at a rate of 16π m/min

Triangle P R Q is shown. Angle R P Q is 39 degrees. The length of P R is 6, the length of R Q is p, and the length of P Q is 8.

KATRIN_1 [288]

According to law of cosines the length of RQ can be written as $p^{2} =6^{2} +8^{2} -2*6*8cos(39)$ .

Given the length PR is 6 , the length of RQ is p, the length of PQ is 8 and the angle RPQ is 39 degrees.

A length of the triangle can be written as according to law of cosines if sides are given and one angle is $a^{2} =b^{2} +c^{2} -2bccos(A)$

We have to just put the values in the above equation.

as $p^{2} =6^{2} +8^{2} -2*6*8cos(39)$ .

p is the side opposite to angle given , the length of other sides are 6 and 8 and angle is 39 degrees.

Hence the side can be written as according to law of cosines if the angle is 39 degrees is as $p^{2} =6^{2} +8^{2} -2*6*8cos(39)$ .
