What does scaled up by a factor of 10 mean?
When enlarging a shape or image, we use a scale factor to tell us how many times bigger we want each line/side to become. For example, if we enlarged a rectangle by scale factor 2, each side would become twice as long. If we enlarged by a scale factor of 10, each side would become 10 times as long.
What is scale factor 10th?
Scale Factor is used to scale shapes in different dimensions. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
How do you find scale and scale factor?
To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.
What is a scale factor Class 10?
Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures.
How do you find the scale factor of 2?
To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.
How do you calculate magnification of an image?
Magnification can be calculated using a scale bar….Scale bar
- Measure the scale bar image (beside drawing) in mm.
- Convert to µm (multiply by 1000).
- Magnification = scale bar image divided by actual scale bar length (written on the scale bar).
What is magnification of lens Class 10?
The ratio of height of image and that of object or ratio of distance of image and distance of object gives magnification. It is generally denoted by ‘m’.
How do you calculate the surface area of a circular cone?
Circular Cone Surface Area Volume = (1/3)πr 2h Lateral Surface Area = πrs = πr√(r 2 + h 2) Base Surface Area = πr 2 Total Surface Area. = L + B = πrs + πr 2 = πr(s + r) = πr(r + √(r 2 + h 2))
How do you find the area of a square with dimensions?
Solved Examples 1 Solution: A = 1386 sq.cm. If the length of the side of a square is 11cm. Then find its area and also find the total length of its boundary. 2 Solution: Area = a2 = 11 2 = 121 sq.cm Total length of its boundary, Perimeter = 4a = 4 x 11 = 44 sq.cm. 3 Solution: Therefore, Area = length x width = 12 x 10 = 120 sq.m.
What is the equation for calculating the area of a circle?
The equation for calculating the area of a circle is as follows: area = πr 2. The Farmer and his Daughter – Circle of Li(f)es
How do you find the area of a rectangular field?
The length of rectangular field is 12m and width is 10m. Find the area of the field along with its perimeter. Therefore, Area = length x width = 12 x 10 = 120 sq.m. Perimeter = 2 (length + width) = 2 x (12 + 10) = 2 x 22 = 44 m. Solve the questions here based on area and perimeter of different shapes.
