You have to find the area of both circle and square first then add the answers u get together.

Quarter circle:
A = 3.14 (radius(^2)
A= 3.14(4^2)
A= 3.14(16)
A=50.24cm ^2

Square:
A = b×h
A = 8×8
A = 64cm^2

Then add the answer together.
64 + 50.24 = 114.24cm ^2

the answer is 114.24 or 114.2

In a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy

Answer:

So, the way a ratio works is "for every 1 of this, we have 4 of this" for example. (the ratio I just described would be 1:4.)

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.

So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.

So:

240 ÷ 3 = 80

If your ratio is 9:3, then 80 is your answer.

Hope this helps and have a nice day!

Answer:

x = 6

Step-by-step explanation:

The area of a triangle is equal to the base times the height divided by two. In this case, the base is 6 (or x, it doesn't really matter) and the height is x (or 6, it doesn't matter). That means that the area of this triangle is equal to 6 * x divided by 2, which is also equal to 18. we can say that 6x/2 = 18, meaning that 6x = 36, so x = 6.
