Equilateral triangle with the side 4 cm and h=2.5 cm
In equilateral triangle all sides are equal
so all sides are equal in the base of the prism
lateral area of the prism = Perimeter of the base * height
Perimeter of the base equilateral triangle = side + side + side
lateral area of the prism =(side + side + side) * height
= (4+4+4) * 2.5
= 
lateral area of the prism = 
2)
2*120 + 2*3.14*40 = 240 + 251.2 = 491.2;
Answer:
0.1
Step-by-step explanation:
0.3 x 7= 2.1
2.1 - 2= 0.1
Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
