Question

Calculate areas or this shape? Confused -.-

Answer 1

What are your options?

Answer 2

I have no options :(

Answer 3

Area of circle= \[pi ~* R * R\]

Answer 4

i know the circle formula for this shape, it's (1/2)(3.14)(8)^2= 100.4

Answer 5

is this right??

Answer 6

why 1/2?

Answer 7

I saw this formula somewhere. Ok so it's (3.14)(8)^2

Answer 8

\[\LARGE Area~of~circle=\pi \times R^2\]

Answer 9

\[\LARGE \pi=3.142857142857143\approx3.14\]

Answer 10

\[\LARGE R=8\]

Answer 11

i know that already, i know pi=3.14
See the shape i drew it has two shapes right, how can calculate the area of both of these shapes??

Answer 12

(3.14)(8)^2=200.96, ok we got the circle.
now how can i calculate the other shape. I have to find the area for both of these shapes and add them together.

Answer 13

\[\LARGE Area ~of ~\square=Total~Area-Area~of~circle\]
