1. A minute hand of a'clock is 16 in long. find the distance traveled by the tip of the minute hand in one hour circumference: ___________

Jawab:

100.5 inch

Penjelasan dengan langkah-langkah:

The radius is 16 inch.

The distance traveled by the tip of the minute hand in one hour is the circumference of the circle = 2× π × 16 = 100.5 inch.

2. The minute hand of a clock is 12 cm long. (a) How far does the tip of the minute hand travel in 25 minutes? (b) How long will it take the tip to move 24 cm?pake cara ya​

Jawaban:

(a) Dalam 1 putaran penuh jam, jarum menit akan bergerak mengelilingi lingkaran dengan jari-jari 12 cm. Keliling lingkaran tersebut dapat dihitung dengan rumus C = 2πr, di mana r adalah jari-jari lingkaran dan π adalah konstanta pi (sekitar 3.14). Maka, keliling lingkaran tersebut adalah:

C = 2πr = 2π(12 cm) ≈ 75.4 cm

Jadi, dalam 1 putaran penuh jam, ujung jarum menit akan bergerak sejauh 75.4 cm. Dalam 25 menit, jarum menit akan bergerak sejauh 25/60 kali putaran penuh jam, atau sekitar 31.4% dari keliling lingkaran. Jadi, jarak yang ditempuh oleh ujung jarum menit dalam 25 menit adalah sekitar:

31.4% x 75.4 cm ≈ 23.7 cm

Jadi, ujung jarum menit akan bergerak sejauh sekitar 23.7 cm dalam 25 menit.

(b) Jarak total yang harus ditempuh oleh ujung jarum menit agar bergerak sejauh 24 cm adalah 24 cm. Dalam 1 putaran penuh jam, ujung jarum menit akan bergerak sejauh 75.4 cm. Oleh karena itu, ujung jarum menit harus berputar sebanyak 24/75.4 putaran penuh jam. Maka waktu yang dibutuhkan untuk bergerak sejauh 24 cm adalah:

(24/75.4) x 60 menit ≈ 19 menit

Jadi, waktu yang dibutuhkan oleh ujung jarum menit untuk bergerak sejauh 24 cm adalah sekitar 19 menit.

3. [tex]\huge{\underline{\frak{\pink{\;Question:\;}}}}[/tex]⠀⠀The minute hand of a circular clock is 15 cm long. How far does the tip of the minute hand move in 1 hour.[tex]\sf{take \: \pi = 3.14}[/tex]Note:- Need full Explanation in English - kindly don't Spam ​

Given:

The minute hand of a circular clock is 15 cm long.

ToFind:

How far does the tip of the minute hand move in 1 hour.

Solution:

[tex]{ \underline{ \frak{As \: we \: know \: that}}}[/tex]

In 1 hour, minute hand completes one round means makes a circle.

Here,

➵ The length of the hand of the clock is 15cm long! so, let's consider the radius of the clock as 15cm

Fromula:

[tex] \longrightarrow \tt \: circumference = 2\pi \: r[/tex]

Where,

π stands for 3.14R stands for the radius!

Calculation,

[tex] \longrightarrow \tt \: circumference = 2\pi \: r \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \longrightarrow \tt \: circumference = 2 \times 3.14 \times 15 \\ \\ \\ \longrightarrow \tt \: circumference = {\boxed{ \tt94.2cm }} \: \: \: \: \: \: \: \: \: \: [/tex]

Henceforth ittravels94.2cm

Penjelasan dengan langkah-langkah:

Given:-

The minute hand of clock is 15cm

ToFind:-

How far distance will be covered in 1 hour

Solution:-

Circumference of Circle = 2πr

= 2 × 3.14 × 15

= 6.28 × 15

= 94.2cm

Hence, 94.2cm is the answer of required Question!

10. The ratio of the area of a square of side 15 cm to that of a rectangle, with the length of 24 cm long, is 5 : 4. What is the breadth of the rectangle?​

Short Answer:

Breadth of the rectangle = 7,5 cm

Step by step Explanations:

Area of square : Area of rectangle = 5 : 4

(Side²) : (length x breadth) = 5 : 4

[tex]\frac{15CM^{2} }{24CMXBreadth}[/tex] = [tex]\frac{5}{4}[/tex]

[tex]\frac{225CM^{2} }{24CMXBreadth}[/tex] = [tex]\frac{5}{4}[/tex]

225 cm² x 4 = 24 cm x breadth x 5

900 cm² = 180 cm x breadth

breadth = 900 cm² : 180 cm

breadth = 7,5 cm
