Air is being pumped into a spherical balloon so that its volume increases at a rate of 150 cm3/s. How fast is the radius of the
Slav-nsk [51]

0.119cm/s is the radius of the balloon increasing when the diameter is 20 cm.

<h3>How big is a circle's radius?</h3>

The radius of a circle is the distance a circle's center from any point along its circumference. Usually, "R" or "r" is used to indicate it.

A circle's diameter cuts through the center and extends from edge to edge, in contrast to a circle's radius, which extends from center to edge. Essentially, a circle is divided in half by its diameter.

dv/dt = 150cm³/s

d = 2r = 20cm

r = 10cm

find dr/dt

Given that the volume of a sphere is calculated using

v = 4/3πr³

Consider both sides of a derivative

d/dt(v) = d/dt( 4/3πr³)

dv/dt =  4/3π(3r²)dr/dt = 4πr²dr/dt

Hence,

dr/dt = 1/4πr².dv/dt

dr/dt = 1/4π×(10)²×150

dr/dt = 1/4π×100×150

dr/dt = 0.119cm/s.

a hiker in africa discovers a skull that contains 43% of its original amount of c-14 Find the age of the skull to the nearest ye
11Alexandr11 [23.1K]
The amount of C-14 at time t is
N(t) = N_{0} e^{-Kt}
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴

When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
e^{-10^{-4}t} = 0.43 \\\\ -10^{-4} t = ln(0.43) \\\\ t = - \frac{ln(0.43)}{10^{-4}} =8439.7 \, years

Answer:
The age of the skull s 8440 years (nearest integer)
