Question

find the length of Arc of a circle with radius 7 cm and the central angle 45 degree​

Answer 1

Here u go ♥️♥️♥️♥️♥️♥️♥️

Formula :

▶️ length of Arc = theta /360×2πR

⏩Given : radius =7cm and central angle =45°

▶️Now, using formula we get,

=> 45°/360°×2×π×7

=> 1/8×2×22/7×7

=> 11/2

=> 5.5 cm

Therefore the length of Arc is 5.5cm

Hope it helps u............✨✨✨✨✨✨♥️♥️♥️♥️✌️✌️✌️

Answer 2

Answer:

Arc Length =    5.5 cm  

Step-by-step explanation:

Here given that

Radius of Circle(r) = 7cm

central angle (Ф) = 45°

Then Arc Length of the circle = (Ф/360)*2πr

 Put the values of  Ф = 45°,   r = 7,   π=$\frac{22}{7}$ ,

Arc Length = $\frac{45}{360}*2*\frac{22}{7}*7$

On solving, We get

Arc Length =    5.5 cm
