Question

Watch help video The radius of a circle is 11cm. Find the circumference to the nearest tenth. Anowe: C= cm subwik Answer

Answer 1

Answer: C = 69.1 cm

Explanation:

Our task is to find the circumference of the circle, given that:

• the radius is 5 cm

Applying the formula,

• 
  `\sf{Circumference=2\pi r}`

Plugging in the values,

• 
  `\sf{C=2\pi*11}`
• 
  `\sf{C=22\pi}`
• 
  `\sf{C=69.1\:cm}`

Therefore, the circumference of the circle to the nearest tenth is 69.1 cm.

Answer 2

69.1 cm

Explanation:

Circumference of circle = 2 · π · r

r = 11 cm

π = 3.14

C = 2 · 3.14 · 11 ≈ 69.1 cm

So, the answer is 69.1 cm
