The radius of a plant cell is approximately 3.125 x 10^-11 meters, whereas that of a red blood cell is about 5 x 10^-6 meters. What is the product of the lengths of the two radii?
The product of the lengths of the two radii is obtained by multiplying the two values:
(3.125 x 10^-11 meters) x (5 x 10^-6 meters).
To multiply these numbers, we can simply add their exponents:
(3.125 x 5) x (10^-11 x 10^-6) = 15.625 x 10^-17.
Since 10^-17 is a very small number, we can represent it in scientific notation by multiplying both parts by 10, resulting in:
(15.625 x 10) x (10^-18) = 156.25 x 10^-18.
Therefore, the product of the lengths of the two radii is 156.25 x 10^-18 meters.
To find the product of the lengths of the radii, you simply need to multiply the two radii together.
Given:
Radius of a plant cell = 3.125 x 10^-11 meters
Radius of a red blood cell = 5 x 10^-6 meters
Product of the lengths of the radii = (3.125 x 10^-11 meters) * (5 x 10^-6 meters)
To multiply the numbers in scientific notation, you multiply the coefficients and add the exponents:
(3.125 * 5) x (10^-11 * 10^-6) = 15.625 x 10^-17 meters
Since 15.625 can be expressed as 1.5625 x 10, the final answer in scientific notation is:
1.5625 x 10^-17 meters.
To find the product of the lengths of the two radii, we simply multiply them together. In this case, we multiply the radius of a plant cell (3.125 x 10^-11 meters) by the radius of a red blood cell (5 x 10^-6 meters).
The general rule when multiplying numbers written in scientific notation is to multiply the numerical parts together and then multiply the powers of 10.
So, the product of the radii would be:
(3.125 x 10^-11 meters) * (5 x 10^-6 meters)
First, multiply the numerical parts:
(3.125 * 5) = 15.625
Next, multiply the powers of 10 by adding the exponents:
(10^-11 meters) * (10^-6 meters) = 10^(-11 + -6) = 10^-17
Putting it all together, the product of the radii is:
15.625 * 10^-17 meters
Therefore, the product of the lengths of the two radii is approximately 1.5625 x 10^-16 meters.
