A triangle with area 10 cm2 is dilated by a factor of 2. What is the area of the dilated image? _________ cm2 a pyramid with the volume of 1000 ft^3 is dilated by a factor of 1.5. What is the volume of the scaled image? A cylinder with the volume 22.8 mm^3 is dilated so that its new volume is 615.6mm^3. By what factor was the cylinder dilated?
Triangle: 10cm² x 2² = 10cm² x 4 = 40 cm² Since the area has an exponent of two. The factor should also be raised to the 2nd power to get the area of the dilated image. Pyramid: 1000ft³ x 1.5³ = 1000ft³ x 3.375 = 3,375ft³ Volume has an exponent of 3. Thus, factor should be raised to the 3rd power to get the volume of the scaled image. Cylinder: 615.60mm³ ÷ 22.80mm³ = 27 dilation of the cylinder: ∛27 = 3 Volume has an exponent of 3. We need to get the cube root of the factor used to dilate the cylinder.
