The surface area of a prism is 24 square feet. What is the surface area of a similar prism that is smaller by a scale of 1/2

12 square feet

Step-by-step explanation:

Just multiply the surface area of the original prism by 1/2 to get your answer (divide by two).

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
