The answer is 567.4 π m².

The surface area of the sphere with radius r is: A = 4 π r²
The volume of the sphere with radius r is: V = 4/3 π r³

Step 1. Calculate the radius from the volume:
V = 4/3 π r³ = 2,254 π m³
r³ = (2,254 π) / (4/3 π)
r³ = 2,254 π/π * 3/4
r³ = 2,254 * 3/4
r³ = 1,690.5
r = ∛1,690.5
r = 11.91 m

Step 2. Calculate the surface area using the r:
A = 4 π r²
A = 4 π 11.91²
A = 567.4 π m²

For every 4 feet of fencing, the cost is $36 <br> 2 4 7. 10<br> 8 36 81
stiv31 [10]
If your amount of fencing was 247.10 then you would divide that by 4 and multiply your result by 36 to find the amount of money needed to build a fence, your result is $2,196, now of course you have have more than 4 feet left but since the problem asks every 4 feet of fencing costs $36, I’m going to assume that if you have more than 4 but less than 8 you get that for free

Audrey uses 5/8 cup of Fruit in each smoothie she makes 6 smoothies to share with her friends how many cups of fruit does she us
olga55 [171]
To find the amount of cups of fruit used you must multiply the number of smoothies (6) by the amount of fruit need for each smoothie (5/8)
6 x 5/8 = 30/8
30/8 can be simplified to 15/4.
This is still an improper fraction, because the numerator is higher than the denominator. To fix this, you divide 15 by 4, which equals 3 3/4 cups

2. 2x - 30 = 12x - 15
3. -10x - 30 = -15
4. -10x = 15
5. x = -10/15
6. x = -2/3 (simplified)

Radium-226 is a metal with a half-life of 1600 years. If you start with 1 kilogram of radium-226, how much will remain after 20,
erica [24]
Ending Amount = Beginning Amount / 2^n 
where 'n' = # of half lives
n = 20,000 / 1,600 = 12.5 half-lives

Ending Amount = 1 kg / 2^12.5
Ending Amount = 1 kg / <span> <span> <span> 5,792.6
