Cancer cells often have a diameter of about20 microns, or 2(10)-5 m. a. Although cancer cells are not exactly spheres, they areclose enough to spheres to make this simplification. Whatis the volume of a cancer cell? b. Suppose a cancer cell doubles every day. Starting with onecancer cell, find a formula for the total volume of the cancer cells after t days. c. Assume that a tumor of cancer cells is roughly a sphere.Also assume that about 74% of the tumor is made up ofcancerous cells, while the rest consists of blood vesselsand space between the cells. How many days must passbefore the single cancer cell grows to a tumor with a diameter of 1 cm (10-2 m)?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Cancer cells often have a diameter of about
20 microns, or 2(10)-5 m.
a. Although cancer cells are not exactly spheres, they are
close enough to spheres to make this simplification. What
is the volume of a cancer cell?
b. Suppose a cancer cell doubles every day. Starting with one
cancer cell, find a formula for the total volume of the cancer cells after t days.
c. Assume that a tumor of cancer cells is roughly a sphere.
Also assume that about 74% of the tumor is made up of
cancerous cells, while the rest consists of blood vessels
and space between the cells. How many days must pass
before the single cancer cell grows to a tumor with a diameter of
1 cm (10-2 m)?
