To determine the area if the circle, you must know the diameter or the radius of a circle.
If you know the radius of a circle, use this as your formula. Remember: Pi (the greek symbol thingy) is equal to 3.1415. (A is equal to area of the circle and r represents the radius)
If you know the diameter, just divide the diameter to get the radius then use the same equation.
Answer:
15.12
Step-by-step explanation:
3.6 x 4.2
first aline the decmials like you would regularly do to multiply.
Then multiply 2 x 6=12 and then 2 x 3=6 and put them down were you would already do noramly multiplying.
and then muliply 4x6=24 and 4x3=12 and do the same thing as you would do normaly and then add 72 and 144 to get 1512 and then count your decmail placing. which is 2 placeing in total which makes 1512 into 15.12
and now you done!
Example of how it should look...
3 . 6
× 4 . 2
+ 7 . 2
+ 1 4 4
= 1 5 1 2
I think it’s the second choice
