What is the circumference of five

if 5 is the radius

(circumference formula is 2*pi*r)

so it'll be 2*pi*5 = 31.41592654...

if 5 is the diameter, then the radius is 2.5 (radius= diameter/2)

so the circumference will be 2*pi*2.5 = 15.70796327

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
