Question

a circular clock face has a diameter of 7 inches how many inches does the tip of the minute hand travel in a day

Answer 1

14π inches

Explanation:

Diameter of the clock = 7 × π = 7π

one day = 24 hours which means

2 clockwise turns around the clock

sooo 7π × 2 = 14π

Answer 2

527.52 in

Explanation:

To answer this question you have to find the circumference of the circle.

You have to use the formula below to find the circumference.

C = π d

Here,

d ⇒ diameter ⇒ 7 in

Let us solve it now.

C = π × d

C = 3.14 × 7

C = 21.98 in

• So, the tip of the minute hand is traveling 21.98 in an hour.
• But they're asked for the distance traveled by the tip of the minute in a day.
• So, to find that we have to multiply the answer by 24 hours.

Let us find it now.

Distance traveled in a day = 21.98 × 24

= 527.52 in
