19,840 pages. You must multiply 20 pages by 31 days which gives you a product of 620 pages. This is the amount of pages each student reads in the month of January. Then, you must multiply 620 pages by 32 students and get a product of 19,840 pages in all.
First to find the area the formula is A=pi(r^2)
so plug in the numbers A= (3.14)(4.5)(4.5)= 63.62 is the total area
150*63.62=9543 9543/360=26.5
So the answer is 26.5 cm ^2
X+y=-1
3x-y=21
add them equations
x+y=-1
<u>3x-y=21 +</u>
4x+0y=20
4x=20
divide by 4
x=5
x+y=-1
5+y=-1
minus 5 both sides
y=-6
(x,y)
(5,-6)
D is answer
There is 45.9 inches for the whole year so
It is 48 cm together because mutiply it
