Please help The circumference of a plate is 10 centimeters. If the radius
of the plate is tripled, what will be the circumference of the
new plate?

The new circumference is 30 pi cm

Step-by-step explanation:

Here, we have that the initial circumference measures 10 pi cm

Mathematically, we have the circumference of a circle as;

C = 2 * pi * r

10 pi = 2 pi r

2r = 10

r = 10/2 = 5

Now, we want to triple the radius

the new radius becomes 5 * 3 = 15

The new circumference is thus;

C = 2 * pi * 15

C = 30 pi cm
