Let's say that the diameter was 1/2 mile. So the diameter is 1/2,  then you need to find the circumference, aka perimeter of the circle. So 1/2 times 3.14 = 1.57 miles So then you would do 1.57/2 = .785 of an hour If you round to nearest tenth The answer is .8 of an hour.

Answer:

It took Latisha <u>0.8 hour</u> to walk all the way around the crater

Step-by-step explanation:

Firstly, we write the parameters which we were given in the question

diameter (d) = 1/2 or 0.5 mile, velocity (v) = 2 miles per hour, π = 3.14

circumference of a circle (C) = 2πr

But 2 x radius ⇒ diameter, hence,

circumference of a circle = πd ⇒ 3.14 x 0.5 = 1.57 miles

C = <u>1.57 miles</u>

Therefore, the circumference of the crater is <u>1.57 miles</u>

To calculate how long it will take her to walk all the way around the crater, divide the distance (circumference of the crater) by speed (velocity). Mathematically represented as:

t = C ÷ v

t = 1.57 ÷ 2 = 0.785 hour

t = <u>0.8 hour</u> (to the nearest tenth)

It took Latisha 0.8 hour (or 48 minutes) to walk all the way around the crater

Write the standard equation of the circle below.
s344n2d4d5 [400]

Answer:

The first answer is correct.

(x + 1)^2 + (y - 2)^2 = 1

A circle with the midpoint M(Mx, My) and the radius r can be written as

(x - Mx)^2 + (y - My)^2 = r^2
