Answer:
46.95 in.²
Step-by-step explanation:
Surface area of the kaleidoscope = surface area of a triangular prism = 2(BA) + P*H
Base area (B) = 2(½*bh) = 2(½*1.5*1.3) = 1.95 in.²
Perimeter of base (P) = 1.5 + 1.5 + 1.5 = 4.5 in.
Height of prism (H) = 10 in.
Plug in the values
Surface area = 1.95 + 4.5*10 = 46.95 in.²

=3.14r^2
Answer:
well the three goes inside the division box and the 4 goes in the outside. Then you see how many times 4 goes into 3 which is 0 then you add a zero next to the three and a decimal point in between the 3 and 0. next, you see how many times 4 goes into 30 which is 7 then you subtract 30-28 which is 2 then you add another 0 and see how many times 4 goes into 20 which is 5 times then you get your answer .75
