Find the approximate surface-area-to-volume ratio of a softball with a radius of 2 inches.

Umnica [9.8K]3 years ago
8 0

Answer:

Option B.

Step-by-step explanation:

We need to find the approximate surface-area-to-volume ratio of a softball.

Surface area of sphere is

A=4\pi r^2

where, r is the radius of sphere.

Volume of sphere is  

V=\dfrac{4}{3}\pi r^3

where, r is the radius of sphere.

The ratio of surface-area-to-volume is

Ratio=\dfrac{A}{V}=\dfrac{4\pi r^2}{\frac{4}{3}\pi r^3}=\dfrac{3}{r}

It is given that the radius of the ball is 2 inches.

Ratio=\dfrac{A}{V}=\dfrac{3}{r}=\dfrac{3}{2}=1.5

Therefore, the correct option is B.

Rearrange the equation so q is the independent variable.<br><br> 9q-4=3r-6<br><br> r = __
erik [133]

Answer:r=3q+2/3

Step-by-step explanation:

Step 1: Flip the equation.

3r-6=9q-4

Step 2: Add 6 to both sides.

3r-6+6=9q-4+6

3r=9q+2

Step 3: Divide both sides by 3.

3r/3=9q+2/3

r=3q+2/3

Hopefully it’s right

The 100th term of ​ 70, 100, 130
fgiga [73]

Answer:

3040

Step-by-step explanation:

given arithmetic progression is

70,100,130,...

here

first term (a)=70

common difference (d)=100-70=30

number of term n=100

using the formula of arithmetic progression

an=a+(n-1)d

a100=70+(100-1)30

a100=70+99×30

a100=70+2970

a100=3040
