Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³

Answer:
(D)Equilateral Triangle
Step-by-step explanation:
Given a circle centre M; and
The measure of major arc JL = 300 degrees
The triangle formed by radii ML and MJ and chord JL is Triangle JLM.
Since ML=MJ (radii of a circle), the base angles are equal.
Therefore:
We can see that all the angles of triangle JLM are 60 degrees, therefore Triangle JLM is an Equilateral Triangle.
If you rotated the box 90º, the orrientation would not be the same, so it is not D or B.
After rotating 180º, the box will be in the 1st quadrant. If it moved along the x-axis, it wouldnt be there anymore, and the after-picture shows it in the first quadrant still, so the only answer it can be is C.
Step-by-step explanation:
4/12=y/9 1/3 so y must equal 3
1.2/m=3/5 1.2x2.5=3 5÷2.5=2 m=2
y/5=13/10 10÷2=5 13÷2=6.5=y
5/10=8/w 5x1.6=8 w=19x1.6=16
