The area of a circle is 28.26 square miles. What is the circle's diameter?

1 answer:

3 0

The diameter is 6. Explanation:

radius: 3.14r^2

28.26=3.14r^2

28.26/3.14=r^2

r^2=9

r=3

and we know that diameter is two times the radius so:

3*2=6

diameter equals 6.

if you want to check it plug back in:

3^2 * 3.14 = 28.26

hope this helped :)

What is the volume of the prism?

Nikitich [7]

Answer:

24 m³

Step-by-step explanation:

We need to find the volume of the prism. Given that , rectangular prism with cubic units arranged in two rows of two with six total layers . And the volume of each unit is 1 m³ .

Volume of one unit :-

$\rm\implies Volume_{one\ unit } = 1m^3$

By Unitary Method :-

Volume of two cubes , will be :-

$\rm\implies Volume_{two\ unit } = 2m^3$

Volume of one layer :-

$\rm\implies Volume_{one\ layer } = 4m^3$

Volume of six layers :-

$\rm\implies Volume_{6\ layers } = 4m^3\times 6 \\\\\rm\implies \boxed{\rm Volume_{6\ layers } = 24 \ m^3}$

1 (4 x 12) + (4 x 8) 2 4 x (12 - 8) 3 (4 x 12) - ( 4 x 8) 4 4 x (12 + 8)

jenyasd209 [6]

Answer: 4 x (12 - 8)

Step-by-step explanation:

the word difference really means exactly what it is saying. it is the quantity difference between two numbers. like, if someone would say, "what's the difference between 4 and 2?' then you would just subtract 2 from 4 to find the difference between the two numbers.

so, we now know that we are going to be subtracting 8 from 12.

plus, it tells us to show 4 times 12 - 8. that means that we will be multiplying (12 - 8) by 4.

so, our only viable option is 4 x (12 - 8).

svet-max [94.6K]

209 action figures on his wall

380/100 = 3.8
so there would be 3.8 action figures per 1%
then 3.8*55 =209

Trevon and his friends are going on a road trip that is 594 7/25 miles long. If they have 89 37/100 miles until their destinatio

Alenkinab [10]

Answer: 504.91 miles

Step-by-step explanation:

From the question, we are told that Trevon and his friends are going on a road trip that is 594 7/25 miles long and that they have 89 37/100 miles to reach their destination. To know how far that they've already traveled, we subtract 89 37/100 from 594 7/25.

= 594 7/25 - 89 37/100

Since the answer should be in decimal, we can change the fractions to decimal.

= 594 7/25 - 89 37/100

= [594 +(7/25 × 100)] - [89 + (37/100 × 100)]

= (594 + 0.28) - (89 + 0.37)

= 594.28 - 89.37

= 504.91 miles

They've already travelled 504.91 miles
