A spherical block of ice melts so that its surface area decreases at a constant rate: ds/dt = - 8 pi cm^2/s. calculate how fast
sveticcg [70]
The rate a which the surface area, S, decreases is
\frac{dS}{dt} =-8 \pi \, cm^{2}/s

The surface area is
S = 4πr²
where r =  the radius at time t.

Therefore
\frac{dS}{dt} = \frac{dS}{dr}  \frac{dr}{dt} =8 \pi r  \frac{dr}{dt} \\\\ -8 \pi  = 8 \pi r  \frac{dr}{dt} \\\\  \frac{dr}{dt} =- \frac{1}{r}

When r = 3 cm, obtain
\frac{dr}{dt}]_{r=3} = - \frac{1}{3} \, cm/s

Answer:  -1/3  cm/s  (or -0.333 cm/s)

Answer:

SAS

Step-by-step explanation:

As per the given diagram, the following facts are evident.

(BR) = (CR), Both sides have two small orange lines on them. This shows that these sides are congruent.

(<B) = (<C), this is shown by the box around both angles, indicating that both angles have a measure of (90) degrees.

(AB) = (AC), Both sides have one small orange line on them. This indicates that these sides are congruent to each other.

Therefore, the sides are congruent by the theorem (SAS); side-angle-side, congruence.
