A million is a thousand thousands :
7,000,000
Hence, B. Keep increasing is the best answer
Total surface area of the square pyramid is 1476 cm².
Step-by-step explanation:
Total surface area of a pyramid = 12pl + B. Here p is perimeter of the base which is a square = 4 × side, l is the slant height and B is the area of the base = side²
Find perimeter of the base
⇒ p = 4 × side = 4 × 6 = 24 cm
Find the slant height of the prism. l² = height² + (side/2)² (Based on Pythagoras Theorem)
⇒ l² = 4² + (6/2)² = 16 + 9 = 25
⇒ l = √25 = 5 cm
Find the area of the base of the pyramid.
⇒ B = side² = 6² = 36 cm²
Calculate total surface area of the pyramid.
⇒ TSA = 12 × 24 × 5 + 36 = 1440 + 36 = 1476 cm²
Geometric mean= √ ( 7 X 9)= √63
= 3√7
Answer:
Formula for both is: A= (h•b)/2
Plug in values for First one are: 16 and 14
Area of first one: 112in^2
Plug in values for Second one: 2 and 3.5
area of second one: 3.5m^2
Step-by-step explanation:
plug in the values-. A= 16•14= 224 224÷2= 112
plug in the values #2- A= 2•3.5= 7 7÷2= 3.5
hope this helps u <3
