What is the radius of a circle whose diameter is 3 1/2 in?

1.75 inches

Step-by-step explanation:

d=2r

Substitute 2.5 in for diameter

3.5=2r

Divide by 2 on both sides

r=1.75 inches

Hope this helps! :)

1.75

Step-by-step explanation:

radius is always half of what the diameter is

3.5 divided by 2 = 1.75

Hope this helps!!

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
