The radius is 4.9 and the Circumference is 9.8π

Step-by-step explanation:

Data:

Diameter = 9.8

Circumference = ?

Radius = ?

Radius

Radius is half of the diameter so radius = $\frac{diameter}{2}$

Radius = $\frac{9.8}{2}$

Radius = 4.9

Circumference

Circumference = 2πr

Circumference = 2π(4.9)

Circumference = 9.8π

Therefore, the radius is 4.9 and the Circumference is 9.8π

Alecu ar citi in 12 zile 14 x 12 = 168 de pagini (atatea pagini are cartea);
