1. Find the Area of the given circle. Round to the nearest tenth.
ruslelena [56]
Hey there Panda!

Question #1

(3.5*3.14 = 10.99 rounded would be 11) 11 is your answer.

Question #2

The circumference equals 21.99, but rounding it would be 22.00

Question #3

We divide 12/2 and from this we get 6. We doing (6*3.14) and then multiply by 2 and then divide by it's circumference and then we get it area. The answer that I got was 452.39, but from looking at your options, your correct answer would be 452.2 (ft)

Question #4

So, by looking at this weird shape, we see that the integer's are 8 by 5. When doing area, we often multiply. As we do this with these number's, we get 40.

We do 8/4 = 2; 5/2 = 2.5. So, from doing this, we get 90.2 (ft).

Question #5

With this last question, I believe that the answer may be C.) So, what I did was I did the radius x's 3.14 and got 6.28 then minus 10 and got around 3.

Hope this helps.

Which statement is true?
Maslowich

Answer:

A

Step-by-step explanation:

on the left of the equation, (6^4)^-5 = 6^-20

the right side you add the exponents so it would be (-7-3) =-10

so it would be 6^-10, which is greater than 6^-20

A transformation T: (x, y) (x - 5, y + 3).
telo118 [61]

A' ( - 3, 2 ) that is B

a translation ( x - 5, y + 3 ) means subtract 5 from the x- coordinate and add 3 to the y-coordinate 3

A(2, - 1 ) → A'(2 - 5, - 1 + 3 ) → A'( - 3, 2 )
