- Describe in square units 4cm2.
Review
Area of square or rectangle.
eg.
A = L x W
A = 6 x 2
A = 12cm2
Parallelogram:
eg.
A = bxh
A = 10 x 5
A = 50cm2
Finding Area of a circle.
Use pieces of circle to create to
a shape very close to a parallelogram.
Close to parallelogram.
h = radius of a circle
b = 1/2 circumference
Ap = b x h
Ao = 2 pi r/2 x r
Ao = pi x r x r
Ao = pi r 2
Find the area of a circle with a radius of 10m. Formula and work.
Ao = pi r 2
Ao = 3.14 x 10 2
Ao = 3.14 x 100
Ao = 314 m2
Find Area of following circles.
Answer for "8 cm":
Ao = pi r 2
Ao = 3.14 x 8 2
Ao = 3.14 x 64
Ao = 200.96cm 2
Answer for "14.8m":
Ao = pi r 2
Ao = 3.14 x 14.5 2
Ao = 3.14 x 219.64
Ao = 687.79cm 2
Answer for "6.8 m":
r = d/2
r = 6.8/2
r = 3.4
Ao = pi r 2
Ao = 3.14 x 3.4 2
Ao = 3.14 x 11.56
Ao = 36.30m 2
Answer for "20 cm":
r = d/2
r = 20/2
Ao = pi x 2
Ao = 3.14 x 10 2
Ao = 3.14 x 100
Ao = 314cm 2

ReplyDeleteI'm sorry that I leave out some spaces. I tried to fix it but it would end up all messed up so i didn't want you guys to get confused. I'll try to do better next time. Please ignore the spaces, thank you!

ReplyDeleteGood job Raelynn! I really liked how you used different colors for some of the words and it's really organized.
ReplyDeleteNice post Raelynn! I like how you use alot of pictures to help us understand your scribe but you should use a little darker colour because it seems like the words are blending in with the backround.But it was still a good post.

ReplyDeleteHello my name is Bryce. I am one of the students from Zagreb. You explained the lesson very well and I can understand what your class is doing. However I believe that you could have explained the math a little bit more.
