Answer:
Explanation:
Two cylinders are similar. The heights of the cylinders are 15 cm and 12 cm. If the surface area of the smaller cylinder is 487 cm square. find the surface area of the larger cylinder.
Height of the smaller cylinder = 12cm
Area of the smaller cylinder = x
Height is the bigger cylinder = 15cm
Area of the bigger cylinder = 487cm²
We can find the radius of the bigger cylinder
Radius of the bigger cylinder = 4.07 cm
Hence: we form our proportion to find radius of Smaller cylinder
12/15 = x/4.07
Cross Multiply
15x = 12 × 4.07
x = 12 × 4.07/15
x = 3.256 cm
