This figure is 14 of a circle.

what is the best approximation for the perimeter of the figure?

use 3.14 to approximate pi.

4.7 cm
7.7 cm
10.7 cm
18.8 cm

18.8cm

Step-by-step explanation:

Multiply 3 by pi.

You get 9.42

Multiply that by 2.

You get 18.84.

Because the perimiter is also known as the circumference and the formula for that is 2rπ

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
