Answer:
Surface area of prism=
Step-by-step explanation:
We are given that surface area of rectangular prism=
We have to write an expression that represents the surface area of prism.
Base of prism is made from length and width
Perimeter of base =2(l+w)
Area of base=lw=Area of top
Surface area of prism=Perimeter of base multiply by height+2 area of base
Because area of base and area of top are equal.
Surface area of prism=Ph+2B=2(l+w)h+2(lw)
Answer:
250 students
Step-by-step explanation:
Given data
Let the total number of students be x
Number of students that plays instrument = 10
Hence
40% of x = 10
40/100*x= 100
0.4x=100
x=100/0.4
x= 250
Hence there are 250 students in total
Answer:
R = sqrt 3 * (V /( pi * h))
V = 62.8
pi = 3.14
h = 15
now we sub
R = sqrt 3 * (62.8 / (3.14 * 15)
R = sqrt 3 * (62.6 / 47.1)
R = sqrt 3 * 1.33
R = sqrt 3.99
R = 1.9 rounds to 2 inches <===
Step-by-step explanation:
Answer:
All Triangles are closed figure polygons that have three straight sides
Step-by-step explanation:
All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.
