Question

the circumferece of a circle having diameter d is. (a) 1/2
$\pi \\ d$
$2\pi \\ d$
$1 \div 2\pi \\ d$

​

Answer 1

↪Fact: Samsung tests phone durability with a but-shaped⬇️

➡️Do these interesting facts have you rethinking everything?

❄ People stash their phones in their back pockets all the time, which is why Samsung created a robot that is shaped like a but—and yes, even wears jeans—to “sit” on their phones to make sure they can take the pressure.

Answer 2

What gave we got?

Diameter of circle= d

Formula:

Circumference of a circle = 2πr or πd

Therefore, answer:

Circumference of a circle having diameter d= πd

OR 2π(d/2) which is ultimately πd

Answer= πd
