Answer:
565.2cm
Step-by-step explanation:
Since we need to find out the circumference because the radius of the tire is 30cm. We take 30cm times 2. Which we get 60cm, then we take 60cm times 3.14 to get the circumference of 188.4cm. Then we take 188.4cm times 3 full rotations to get 565.2cm.
Answer: (x - 2)² + (y - 3)² = 4
<u>Step-by-step explanation:</u>
The equation of a circle is: (x - h)² + (y - k)² = r² where
- (h, k) is the center of the circle
- r is the radius of the circle.
Given: (h, k) = (2, 3) and (x, y) = (2, 1)
Input those values to find r²:
(x - h)² + (y - k)² = r²
(2 - 2)² + (1 - 3)² = r²
0 + 4 = r²
4 = r²
Now input (h, k) = (2, 3) and r² = 4 into the equation of a circle:
(x - h)² + (y - k)² = r²
(x - 2)² + (y - 3)² = 4

I don't think so because I tried it and that's what I got
Step-by-step explanation:
Answer:
(d − 3) (d + 3) (d² + 9)
Step-by-step explanation:
d⁴ − 81
Factor using difference of squares.
(d² − 9) (d² + 9)
Factor using difference of squares again.
(d − 3) (d + 3) (d² + 9)
