A circle has a radius of 3 miles. Use the work shown below to identify the area in terms of pi and the approximate area of the circle. Use 3.14 for π and round the answer to the nearest tenth. A = πr2 A = π(3 mi)2 A = 3.14(9 mi) The area in terms of pi is Pi mi2. The approximated value for the area is .

Given:

Given that the radius of circle is 3 miles.

We need to determine the area of the circle.

Area of the circle:

The area of the circle can be determined using the formula,

where r is the radius of the circle.

Substituting π = 3.14 and r = 3 in the above formula, we get;

Simplifying, we get;

Multiplying, we have;

Rounding off to the nearest tenth, we get;

Thus, the area of the circle is 28.3 square miles.

(x) - (y) = (1 + 4i)

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.
