Answer:
228cm^2
Step-by-step explanation:
Formulas we'll use: area of a rectangle is length x width, and area of a triangle = 1/2x base x height
the base is a rectangle, 10 by 3 cm. 10 x 3 = 30cm^2
the sides are also rectangles, 13 by 3 cm. 13 x 3 = 39, but there are 2 of them, 39 x 2 = 78cm^2
The top and bottom are triangles, 1/2(10)(12) = 1/2(120) = 60, but there are 2 of them, 60 x 2 = 120cm^2
Add up the areas to get your total surface area. It's in square cm
30 + 78 + 120 = 228cm^2
The explanation can be seen above:)

Step-by-step explanation:
Volume of a hemisphere = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]
=> 18π = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]
=> 18 = [tex]\frac{2}{3}[/tex][tex]r^{3}[/tex]
=> [tex]r^{3}[/tex] = 18 × [tex]\frac{3}{2}[/tex]
=> [tex]r^{3}[/tex] = 27
=> r = [tex]\sqrt[3]{27}[/tex]
=> r = 3 inches
Therefore, the radius of the hemisphere in inches is 3 inches.

find surface area of the square pyramid!!! pls i need help with explaining!!!!!
Answers
Answer:
39 square yards
Step-by-step explanation:
The base is a square, so the area is 3 x 3 = 9.
Each side is a triangle, and the formula for that is (1/2)(base)(height)
The base of each side is 3 and the height of each is 5. There are 4 of those, so it's 4 x (1/2)(3)(5) = (2)(3)(5) = 30
Add the base and sides
30 + 9 = 39
Answer:
39 yards
Step-by-step explanation:
surface area = A + [tex]\frac{1}{2}[/tex] ps
A = area of the base
p = perimeter of the base
s = slant height
the base of the pyramid is a square, all sides and angles are equal
; 3 yards
; area of a square = l x w
; area of the base = 9 yd (A)
perimeter of the base ; 3 + 3 + 3 + 3 = 12 yd (p)
slant height = 5 yd (s)
; sub it into the formula
surface area = 9 + [tex]\frac{1}{2}[/tex] x 12 x 5
surface area = 39 yd

Using the tip, (4+5=9 is equal to 5+4=9), just switch the two numbers that add up to 888. So instead of 136+752=888, do 752+136=888 because both of those add up to the same number.
