Answer:
A) The side is 14 cm
B) The total distance around the whoole board is 56 cm
Step-by-step explanation:
So we know its a square.
A square is all equal sides
We got the area which is 196
So we know area of a square is L*W or S^2
And since all sides are equal we can square root 196
That would give you 14
So we know each side is 14
Part B is just perimeter, there are 4 equal sides so we can just multiply 14*4 which is 56.
CHECK:
So we want to check the sides are equal
Each side is 14
and area is 196
14*14=196
So its true
Answer: 168.5 inches
50 yards = 1800 inches
50 meters = 1968.5 inches.
So, if you run 50 yards, you run 1968.5 - 1800, 168.5 inches less than 50 meters.
Let me know if this helps!
We can find the area of the circles on top and bottom using pi*r^2
pi*1^2 = pi.. we have two circles so the total area is 2pi
For the remainder of the cylinder, let's flatten the tube into a rectangle. Imagine cutting a toilet paper roll and laying it flat. The height is given as 9, and the width is the circumference of the circle. C=2pi*r
So the area of the rectangle is 9*2pi*1 = 18pi
Add the 18pi and 2 pi for a total surface area of 20pi.
