B. 61 cm
C. 40 cm
D. 84 cm




Sagot :

DIAMETER

Answer:

  • Option C. 40 cm

— If the radius is 20 cm, the diameter will be 40cm.

— — — — — — — — — —

Step-by-step explanation:

The given radius is 20 centimeters... so,

In order to get the diameter, multiply the given radius by 2 (since radius is one-half of the diameter).

  • 20 × 2 = 40

Hence, the diameter is 40 cm.
