Here is the formula for finding area of a sector:

A = $\pi r^{2}$ × θ° ÷ 360°

where theta is the angle of the sector you wish to find, and r is the radius of the circle.

Substitute the numbers in and you get:

$\frac{25\pi }{2} unit ^{2}$

You should find 39.26991 as your answer (or any number rounded according to the value of pi)

Joe’s annual income has been increasing each year by the same dollar amount the first year his income was 19,500. 8 years later

Anna007 [38]

Answer:

The question is either poorly constructed or it is a trick question. We do not know "In what year was his income 30,300" because the years correlating to his income are not disclosed. Even assuming the question was meant to be posed as "how many years later was his income 30,300" it is still flawed.

Step-by-step explanation:

To arrive at Joe's annual income increase, first subtract 19,500 from 27,900 to get 8400, which is his overall increase over the 8 years. Now divide 8400 by 8. You will get 1050. Beginning with his income of 27,900, add 1,050 to each successive income amount and you will get the following progression:

27,900, 28,950, 30,000, 31,050, 32,100, 33,150, 34,200, 35,250, 36,300.

Therefore, two years after his income was 27,900 it would be 30,000 and 6 years after that it would be 36,300. It would never be 30,300.

Volumeprism=volumecube times number of cubes
vprism/vcube=number of cubes

vprism=12*5*4.25=255
vcube=side^3=(1/4)^3=1/64

vprism/vcube=255/(1/64)=255*64=16320 cubes

There are nine men and ten women in a club; in how many ways can a committee of four be formed?

DochEvi [55]

There are 19 people total, and groups of four are being asked of us. We can use the formula for permutations or combinations.

Permutations: $\frac{n!}{(n-r)!}$
Combinations: $\frac{n!}{r!(n-r)!}$
Where in both scenarios, there are <em>n</em> objects being chosen at <em>r</em> times.

19 P 4 is 93024
19 C 4 is 3876
It all depends on whether order matters with group placement; if it does, your answer is 93024, if not, then your answer is 3876.
