Answer:

V = 904.32 ft^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The radius is 6 and pi = 3.14

V = 4/3 ( 3.14) (6)^3

V = 904.31999 ft^3

Rounding to the hundredths place

V = 904.32 ft^3

Find the area of the figure. Round to the nearest tenth.
Alinara [238K]
To get the area of the half circle, do π r². 
Let's use 3.14 as pi. 
First square 2 to get 4 then multiply it by 3.14 to get 12.56. Since this is a half circle we have to divide it by 2 for the area: 6.28. 
Then for the triangle multiply 6 times 2 (12) then divide it by 2 to get 6. Then add the two together to get 12.28 then round to the nearest tenth to get a final answer of 12.3 m². Hope this helps!

B. After a 25% discount, the price of a T-shirt was $12. What was the price before
Kipish [7]

The price before  the discount is $ 16

The population last year is 5280

<h3><u>Solution:</u></h3>

<u><em>B) After a 25% discount, the price of a T-shirt was $12. What was the price before  the discount?</em></u>

Given that after a 25% discount, the price of a T-shirt was $12.  

We have to find what was the price before the discount?  

Now, we know that,

original price – discount = selling price

Original price – 25% of original price = $12

Let the original price be "a"

\begin{array}{l}{\mathrm{a}-25 \% \text { of } \mathrm{a}=12} \\\\ {a-\frac{25}{100} \times a=12} \\\\ {a\left(1-\frac{25}{100}\right)=12} \\\\ {a\left(1-\frac{1}{4}\right)=12} \\\\ {a\left(1-\frac{1}{4}\right)=12} \\\\ {a\left(\frac{3}{4}\right)=12} \\\\ {a=12 \times \frac{4}{3}=16}\end{array}

Thus the original price is $ 16

<em><u>C) Compared to last year, the population of Boom Town has increased by 25%. The  population is now 6,600. What was the population last year?</u></em>

Last year population + 25% of last year population = present population.

\begin{array}{l}{ \text { Last year population( }100 \%+25 \%)=6600} \\\\ {\text { Last year population } \times 125 \%=6600} \\\\ {\text { Last year population } \frac{125}{100}=6600} \\\\ {\text { Last year population }=6600 \times \frac{4}{5}} \\\\ {\text { Last year population }=660 \times 2 \times 4} \\\\ {\text { Last year population }=5280}\end{array}

Thus the last year population is 5280

what is the approximate result of converting 20 centimeters into inches? remember that 1 inch =2.54 centimeters
luda_lava [24]

Answer:

7.87 inches.

Step-by-step explanation:

We are asked to convert 20 centimeters into inches.

We know that 1 inch equals 2.54 centimeters.

To convert 20 centimeters into inches, we will divide 20 by 2.54 as:

\text{20 inches}=\frac{20}{2.54}\text{ inch}

\text{20 inches}=7.874\text{ inch}

\text{20 inches}\approx 7.87\text{ inch}

Therefore 20 inches are equal to 7.87 inches.
