4. A watermelon is assumed to be spherical in shape while it is growing. Its mass, M kg, and radius,r cm, are related by the formula M = kr3, where k is a constant. It is also assumed that the radius isincreasing at a constant rate of 0.1 centimetres per day. On a particular day the radius is 10 cm andthe mass is 3.2 kg. Find the value of k and the rate at which the mass is increasing on this day.

maaf kalo salahcan u explain it with a details
5. The safe radius, v m/s, at which a train can round a curve of radius r is directly proportional to the square root of r. It is given that the safe speed at which a train can round a curve of radius 256 m is 80 m/s. find the safe speed if the curve has a radius of 225 m.
since safe velocity (v) is directly proportional to the square root of radius (r), so we can conclude that
[tex]
v=c\cdot\sqrt{r}
[/tex]
whereas [tex]c[/tex] is particular constant related to the equation.
Now, by substituing [tex]v=80[/tex] and [tex]r=256[/tex] we will find out the constant [tex]c[/tex]
[tex]
\begin{aligned}
v&=c\cdot\sqrt{r}\\
80&=c\cdot\sqrt{256}\\
80&=c\cdot16\\
\therefore c&=5
\end{aligned}
[/tex]
Now, for [tex]r=225[/tex] m, we have
[tex]\begin{aligned}
v&=c\cdot\sqrt{r}\\
&=5\cdot\sqrt{225}\\
&=5\cdot15\\
&=75
\end{aligned}[/tex]
So, the safe velocity for radius 225 m is 75 m/s

6. 3. Bacteria has a lot of shape. there are spherical, spiral and rod-like. send me a picture of bacteria with spherical shape. and also its name
Neisseria gonorrhoeae and Staphylococcus aureus
Penjelasan:
A spherical bacterium is round or also called coccus (plural : cocci)
Neisseria gonorrhoeae and Staphylococcus aureus both are spherical in shape.
7. given that the mass m of a sphere is directly proportional to the cube of its radius r, and m=54 when r=3, find the value of m when r=4
Jawab:
m=128
Penjelasan dengan langkah-langkah:
find the k first,
[tex]m=kr^{3}\\54=k(3^{3})\\k=\frac{54}{27}\\k=2\\[/tex]
then the equation now complete,
[tex]m=2r^{3}\\[/tex]
input r=4 to get m,
[tex]m=2(4^{3})\\m=128[/tex]

16. the area of a sphere with a radius of 3,5 cm is ..... cm
Area = 4.pi.r^2 = 4.22/7.3,5^2 = 154 cm^2
17. The gravitational force of a satellite on the surface of the Earth of radius R is F. What is the gravitational force on the satellite when its height is R above the Earth?
Jawaban:
F/4
Penjelasan:
h = distance from earth core to satellite
h = R+R = 2R
Fb = gravitational force on the satellite when its height is R above the Earth
F = G m / R^2
Fb = GM m / (2R)2
Fb = GM m / 4R2
Fb = (GM m / R2) / 4
Fb = F/4
18. the area of a circle of radius 49 cm is
