John has a cylindrical water tank in his house with a 4 m radius and 15 m height. The cost of filling the water in the tank is $0.5 per cubic meter. What would be the cost of filling the complete tank? (Use pi = 3.14)

$377

Step-by-step explanation:

Volume of a cylinder is;

V = πr²h

Where;

r is radius

h is height

We are given;

radius; r = 4 m

Height; h = 15 m

Thus;

V = π × 4² × 15

V = 753.9822 m³

Cost of filling the tank is $0.5 per m³.

Thus, total cost to fill this tank is;

C = 0.5 × 753.9822

C = 376.9911

C ≈ $377

answer: was that a question or answer?

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
