A number is a solution when it fits within the range of answers that the function generates.
Given:
Radius of the sphere = 10 in
To find:
The surface area of a sphere
Solution:
Surface area of sphere:



in²
The surface area of a sphere is 400π in².
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
Step-by-step explanation:
picking 3 consonants and 2 vowels when 5 letters are picked (without replacement) from a set of alphabet tiles.
There are 26 letters in alphabet
number of consonants = 21 and number of vowels = 5
We need to pick 3 consonants from 21 consonants
Probability of picking 1 consonant from 26 alphabets = 21/ 26
after picking 1 consonant then number of consonant becomes 20
Probability of picking second consonant from 25 alphabets = 20/ 25
Probability of picking third consonant from 24 alphabets = 19/ 24
We need to pick 2 vowels from 5 vowels
Probability of picking 1 vowel from remaining 23 alphabets = 5/ 23
Probability of picking second vowel from remaining 22 alphabets = 4/ 22
Now multiply all the probabilities

= 0.02022
The team scored twenty-three points in total.
This word sum can be worked out as follows:
Three field goals worth three points each is equal to nine points (3 x 3 = 9).
Two touchdowns were scored; each touchdown is worth six points. This equals twelve points (2 x 6 = 12).
Lastly, the team was awarded a bonus point for each touchdown they scored. They scored two touchdowns so they were awarded two extra points (2 x 1 = 2).
Therefore, we have three subtotals: nine for the field goals; twelve for the touchdowns and two for the bonus points. The equation for this word sum is 9 + 12 + 2 = 23
