Question

Does anybody have this? ill mark brainiest. (quiz)

Answer 1

Formulae Used :-

Circumference of Circle :-

$\sf \underline{\pink{\boxed{2\pi r}}}$

Value of π (pi) =

$\sf \: { \frac{22}{7} } \: or \: 3.14$

Answer :-

9) C = 2πr = 2 × 3.14 × 4

≈ 25.13274

10) C = 2πr = 2 × 3.14 × 7.2

≈ 45.23893

11) C = 2πr = 2 × 3.14 × 10

≈ 62.83185

12) C = 2πr = 2 × 3.14 × 3.6

≈ 22.61947

13) Given :-

Diameter : 8m

Radius = half of D = 4 cm

⇢C = 2πr = 2 × 3.14 × 4

≈ 25.13274

14) Radius = 6 cm

C = 2πr = 2 × 3.14 × 6

≈ 37.69911

15) C = 2πr = 2 × 3.14 × 7.1

≈ 44.61

16) C=2πr=2× 3.14 × 5.2

≈ 32.6
