Every dimension of a triangular pyramid is multiplied by 10 to produce a new figure that is geometrically similar. What effect d
oes this have on the surface area of the pyramid? A.
The surface area of the pyramid is multiplied by 10.
B.
The surface area of the pyramid is multiplied by 50.
C.
The surface area of the pyramid is multiplied by 100.
D.
The surface area of the pyramid is multiplied by 1,000.
E.
The effect on the surface area cannot be determined.
Since the question is asking for surface area and the dimensions are multiplied by 10, the surface area is multiplied by 10^2, or 100. (For area it would be 10^3, or 1000)
The decimal .53 has the 3 in the hundredths place, so the fraction that this was originally is . When you divide 53 by 100 on your calculator, you will get backk .53
