How do you find the surface area of a banana?
The prediction equations obtained using plan area measurements are Weight (g) = 1.866×plan area (cm2) – 5.9649; Volume (cm3) = 1.8518×plan area (cm2) – 11.978; Surface area (cm2) = 1.5568×plan area (cm2) – 47.737.
How do you measure the volume of a banana?
The volume of banana can be measured using measuring cylinder. Take a measuring cylinder & fill almost half water in it and measure, consider it as ‘a’. Then tie a banana to the thin cotton thread and dip in the measuring cylinder. The increased level of water is considered as ‘b’.
What is the density of a banana?
about 1 g/cm3
Say that an average banana is 150 grams (0.15 kg) with a density of about 1 g/cm3 (1000 kg/m3).
What is the volume of an apple?
187 cm3
“Volume of a typical apple is 1.87 dl = 187 cm3.
How can you measure the length of a banana explain?
A simple tip to determine the approximate size of a banana is to stretch your thumb and pinkie finger. If your banana is bigger than that, it is larger than 1 serve. Or if you have a pencil handy, the length of the average pencil will give you the right size.
How do you find area in calculus?
The area under a curve between two points can be found by doing a definite integral between the two points. To find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b. Areas under the x-axis will come out negative and areas above the x-axis will be positive.
What are 3 ways to find volume?
To illustrate the effects of precision on data, volumes will be determined by three different methods: geometrically (measuring lengths); water displacement; and pycnometry. The composition of a mixed brass-aluminum cylinder and the volume of empty space within a hollow cylinder will also be found.
What is the average volume of a banana?
about 110 mL
This is the volume of the banana, which came to be about 110 mL or cm^3.
We traced the banana on graph paper, plotted points on the line, and created equations for the cross section of the banana. Here is the graph on desmos: https://www.desmos.com/calculator/jfertkhwnv We measured the actual volume of the banana, using a water displacement method. The actual volume of the banana is 160cm^3
How do you calculate the surface area of a conical frustum?
The surface area of a solid, right conical frustum is the sum of the areas of its two circular ends and that of its lateral face: circular end SA = π (R 2 + r 2) lateral SA = π (R+r)√ (R-r)2 + h2. total SA = π (R 2 + r 2) + π (R+r)√ (R-r)2 + h2. where R and r are radii of the ends, h is height.
How do you calculate the volume of a rectangular box?
The objective function is the formula for the volume of a rectangular box: The constraint equation is the total surface area of the tank (since the surface area determines the amount of glass we’ll use). The surface area is simply the sum of the areas of the sides and bottom (the top is open). inch tank gives us the maximum volume.
How do you find the volume of a disk?
For volumes we will use disks on each subinterval to approximate the area. The area of the face of each disk is given by A(x∗ i) A ( x i ∗) and the volume of each disk is So, in this case the volume will be the integral of the cross-sectional area at any x x, A(x) A ( x).
