If the radius of a circle is doubled the how does that effect the area?
The area of the circle will be 4 times greater
What effect does tripling the radius and doubling the height of a cone have on the cone's volume?
the volume changes as radius squared and linear with height, so tripling radius and double of height gives 3 x 3 x 2 = 18 times more volume
What is 105 degrees on a radian unit circle?
105 deg = 1.8326 radians approx. The radius of the circle has no effect on the measurement of angles.
How do you get the diameter from the radius?
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
How you get the area of a circle?
A= Area of the circle¶= Pi (About 3.14)r= Radius squared (Radius times radius)3.14 * Radius squared
What was the FEV1 at a radius of 5.00 mm?
The FEV1 (%) at a radius of 5 mm is 73.9% (3541/4791 X 100%).
What was the fev 1 at the initial radius of 5.00mm?
The FEV1 value at an initial radius of 5.00 mm would depend on the specific pulmonary function test results for an individual. FEV1, or Forced Expiratory Volume in one second, is a measure of lung function that can be influenced by various factors like age, sex, and overall health. Therefore, without additional information, it is not possible to determine the exact FEV1 value at a specific initial radius.
What creates a greater change in volume for a cylinder changing only the radius or changing only the height?
Changing the radius.
What does FEV1 stand for?
Forced expiratory volume
How much of an increase in FEV1 do you think is required for it to be considered significantly improved by the medication?
FEV1 is an index that is used to determine how much restrictive or obstructive lung disease is present in a person's lungs. If the FEV1 level is 70% or less then it is standard practice for medication to be given.
What happened to the FEV1 percent as the radius of the airways was decreased?
FEV 1 (%) will decrease as the airway radius is decreased. FEV 1 (%) is the amount of air that can be expelled from the lungs in one second during forced expiration. If the airway becomes smaller, then the resistance to airflow will increase and FEV 1 (%) will become lower.
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
What does fev1 mean?
FEV1 stands for Forced Expiratory Volume in 1 second, which is a measure of lung function. It indicates the amount of air a person can forcefully exhale in one second after taking a deep breath. FEV1 is commonly used in assessing respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).
What effects the cylinder more doubling the radius or doubling the height?
They both have the same effect on the surface area of the pipe, but the radius has more effect on its volume/capacity.
Can you lift a bronco 2 4 inches with out changing radius arms?
yes, you just need the drop brackets for the radius arms
What are the factors that affect FEV1?
Factors that can affect FEV1 (forced expiratory volume in one second) include age, gender, lung size, airway obstruction, smoking, and certain medical conditions such as asthma or chronic obstructive pulmonary disease (COPD). Regular physical activity and maintaining a healthy lifestyle can also influence FEV1.
How accurate are different types of flow meters in measuring FEV1?
Peak flow meters are less accurate in measuring FEV1 compared to spirometers. In general, spirometers are the gold standard for accurately measuring FEV1. Additionally, the accuracy of flow meters can depend on proper technique and calibration.
