Answer:
324π in²
Step-by-step explanation:
The surface area of a sphere = 4πr² ( r is the radius )
Calculate r using the volume (V) formula
V = 
πr³
Here V = 972π , thus
πr³ = 972π ( divide both sides by π )
r³ = 972 ( multiply both sides by 3 to clear the fraction )
4r³ = 2916 ( divide both sides by 4 )
r³ = 729 ( take the cube root of both sides )
r = ![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
= 9
Thus
surface area = 4π × 9² = 4π × 81 = 324π in²

Answer:
Step 2
18 over 8 to a decimal is 2.25
Step-by-step explanation:
Step 1, 20, subtract 16 labeled as
Step 2, 40 labeled as
Step 3, subtract 40, and 0 labeled as Step 4.
Divisor = 8
Divided = 18
Quotient = 2.25
2.25
8 √18
- 16
2 0
- 16
4 0
- 40
0
The first error is at step 2
18 over 8 to a decimal is 2.25

You have a 1/2 chance of spinning an even number on the spinner, and a 1/2 chance of rolling an odd number on the die, 1/2 times 1/2 give you a 1/4 chance of doing both of those tasks.
