Given:
A prism with height 5 cm and equilateral triangular base with side 2 cm.
To find:
The total surface area of the prism.
Solution:
Area of an equilateral triangle is:
Where, a is the side length.
Putting 
, we get
The base and top of the prism are congruent so their area must be equal.
The lateral surface area of the prism is:
Where, P is the perimeter of the base and h is the height of the prism.
The lateral surface area of the prism is:
Now, the total surface area is the sum of areas of bases and lateral surface area.
Therefore, the total surface area is 33.46 cm².
Answer:
6x + 14 ≥ 28
Step-by-step explanation:
6 times a number (6x)
14 more than (so, add 14 to 6x)
greater than or equal to, so this symbol ≥
= 6x + 14 ≥ 28
SOLVED:
6x≥14
x≥2.333333333333333
The answer to this depends on the angle at which they intersect. If it intersects<span> the cylinder perpendicular to the axis then a circle is formed. </span><span>If the plane intersects the cylinder at an angle, it will form an ellipse. This will be true until the plan is parallel with the axis of the cylinder. At that point, the surface will become a rectangle.</span>
Answer:
30 short cakes
Step-by-step explanation:
25ml = 10ml + 10ml +5ml
each 10ml of milk can make us 12 short cakes
we can two 10ml of milk (20ml) which can make us 24 short cakes.
but we have 25 ml of milk so how much does 5ml of milk give us if 10ml of milk gives us 12 short cakes ?
5ml makes us 6 short cakes. 24 short cakes plus 6 short cakes =30 shortcakes.
25ml of milk =10ml(12shortcakes)+ 10ml(12 shortcakes)+5ml(6 shortcakes)
