Answer:

402 cm.

Step-by-step explanation:

To find this, we will need to calculate the circumference of the reel. We can do this using the formula $C = d\pi$ .

Since the radius is 4 cm, the diameter is 8 cm. Put this into the equation to solve for the circumference:

$C = 8\pi = 25.12$

Since the reel spun 16 times, simply multiply the circumference by 16 to get:

25.12 × 16 = 401.92

≈ 402 cm.

Answer:

There was a increase of 1.7% over these three years

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: $\frac{100-a}{100}$

For a increase of a%, we multiply by: $\frac{100+a}{100}$

What was the percentage increase/decrease of groundhogs over these three years?

Decrease of 12%(multiplication by 0.88).

Increase of 6%(multiplication by 1.06).

Increase of 9%(multiplication by 1.09).

After these three years:

0.88*1.06*1.09 = 1.017

1.017 - 1 = 0.017

0.017*100% = 1.7%

There was a increase of 1.7% over these three years

Step-by-step explanation:

3(2) = 3 × 2 = 6
Plug 6 in: 12 + {10 ÷ [11 - 6]}
11 - 6 = 5
Plug 5 in: 12 + {10 ÷ 5}
10 ÷ 5 = 2
Plug 2 in: 12 + 2
12 + 2 = 14
