Answer:

Volume of the hemisphere = \frac{2}{3}\pi r^{3}

Step-by-step explanation:

It's a picture of a globe and a globe of the Earth is in the shape of a sphere.

We know equator divides the earth into two equal halves and these equal halves are called as "hemisphere".

Therefore, a line joining the two extreme points of the diameter of the Earth divides the Earth into two hemispheres.

If the radius of the Earth is 'r',

Volume of the hemisphere = \frac{2}{3}\pi r^{3}

This question is not correctly written.

Complete Question

Select all equations that can represent the question: "How many groups of 4/5 are in 1?" A ?⋅1=4/5? Times 1 is equal to 4 fifths B 1⋅4/5=?1 times 4 fifths is equal to ? C 4/5÷1=?4 fifths divided by 1 is equal to ? D ?⋅4/5=1? Times 4 fifths is equal to 1 E 1÷4/5=?1 divided by 4 fifths is equal to ?

Answer:

D ?⋅4/5=1 = ? Times 4 fifths is equal to

E 1÷4/5=? = 1 divided by 4 fifths is equal to

Step-by-step explanation:

How many groups of 4/5 are in 1?

The operation used to solve this is that Division operation.

Hence, we solve it by saying:

1 ÷ 4/5 = ?

= 1× 5/4 = ?

5/4 = ?

Cross Multiply

5 = 4 × ?

? = 5/4

The equations that can represent the question: is

Option D ?⋅4/5=1 = ? Times 4 fifths is equal to

Option E 1÷4/5=? = 1 divided by 4 fifths is equal to

Situation:
FromTheMoon [43]

Answer:

5.6 days

Step-by-step explanation:

We are given;

Initial Mass; N_o = 25 g

Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)

k = 0.1229

Formula is given as;

N_t = N_o•e^(-kt)

Plugging in the relevant values;

12.5 = 25 × e^(-0.1229t)

e^(-0.1229t) = 12.5/25

e^(-0.1229t) = 0.5

(-0.1229t) = In 0.5

-0.1229t = -0.6931

t = -0.6931/-0.1229

t = 5.6 days

Urgent!!!! not worried about a but i need b and #4
Oksi-84 [34.3K]

b) The surface area is 564.5. Picture below.

4. Three possibilities.

Formula for volume of a cylinder: πr^2h

Formula for volume of sphere: 4/3πr^3

If the radius of the sphere is 1 inch than the volume is: 4.18879 or 4.19 rounded.

I used substitution on this website https://www.omnicalculator.com/math/volume

Just plug in the 4.18879 at the cylinder volume and put in a random number in the radius or height whichever you want then it'll give you the one you left blank. You'll find three possibilities for the radius and height of 4.18879 volume.
