You are filling up a cylindrical tank with a radius of 5m with water at a rate of 3 cm^3/min. Unbeknownst to you the tank has a

Umnica [9.8K]

Answer:

dh/dt = 3/25π m/min

Step-by-step explanation:

Radius = 5m

Rate (dV/dt) = 3 cm^3 / min

Leaking rate = 1 cm^3 / min

Volume = πr^2h

Volume = π(5)^2h

V= 25πh

Differentiate volume implicitly with respect to time

dV/dt = 3 cm^3/min

3 = 25π(dh/dt)

dh/dt = 3 m^3/min /25πm^2

dh/dt = 3/25πm/min

Convert the following metric units of weight. a. 40 centigrams to grams b. 53 milligrams to grams c. 0.54 grams to decigrams d.

liubo4ka [24]

Answer:

a) $0.4$ grams

b) $0.053$ grams

c) $5.4$ decigrams

d) $2300$ milligrams

Step-by-step explanation:

To convert centigrams to grams you have to divide by 100.

$40$ centigrams = $\frac{40}{100}$ grams

= $0.4$ grams

To convert milligrams to grams you have to divide by 1000.

$53$ milligrams = $\frac{53}{1000}$ grams

= $0.053$ grams

To convert grams to decigrams you have to multiply by 10.

$0.54$ grams = $0.54*10$ decigrams

= $5.4$ decigrams

To convert grams to milligrams you have to multiply by 1000.

$2.3$ grams = $2.3*1000$ milligrams

= $2300$ milligrams
