Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal
cricket20 [7]

Answer:

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

C=\frac{1}{2}\pi D

where

D is the diameter of the semicircle

we have

D=10\ units

substitute

C=\frac{1}{2}\pi (10)

C=5 \pi\ units ----> exact value

Assume

\pi =3.14

C=5(3.14)=15.7\ units ----> approximate value

therefore

The arc length of the semicircle is 5 \pi\ units or 15.7\ units

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
