Step-by-step explanation:
circumference=πd
22/7×4
12.57
perimeter=12.57+9+9+2+6
= 38.57
area=6×9=54
1/2πr2
1/2×22/7×4×4
=25.14
54-25.14
area=28.86cm2
FInd the height of the box by dividing the volume by 7 x 5 ( length x width)
Height = 105 / 35
Height = 3cm
There are 6 sides to a box.
Surface area = 2 x length x width + 2 x length x height + 2 times height x width
SA = 2*7*5 + 2*7*3 + 2*5*3
SA = 70 + 42 + 30
SA = 142 cm^2
Answer:
yes
Step-by-step explanation:
there is a single x value for every y value
-2x + 6 - 13x + 16
= -15x + 22
Here you will divide 500 by 6 to get the girl students, and 500 by 5 to get boys.
