Option A

The radius of circle is 19.90 cm

The formula for circumference of circle is given as:

Where,

"C" is the circumference of circle

"r" is the radius of circle

is a constant equal to 3.14

Given that, circumference = 125 cm

To find: Radius of circle

Substitute the given value of "C" = 125 in formula

Thus radius of circle is 19.90 cm

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
