Hans opens a circular window that is 3.5 feet across at its widest point. What is the circumference of the window to the nearest whole number ? Use 3.14 for pi.

10.99 feet

Step-by-step explanation:

pi=3.14

r=3.5\2=1.75

now,

circumference=1*pi*r=2*3.14*1.7510.99 feet

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)
