Answer:
The answer to your question is Area = 39.15 in²
Step-by-step explanation:
Data
See the picture below
Process
1.- Calculate the area of rectangle 1
Area = base x height
Area = (8.8)(6.55 - 4.3)
Area = (8.8)(2.25)
Area = 19.8 in²
2.- Calculate the area of rectangle 2
Area = (4.3)(2.25)
Area = 9.675 in²
3.- Calculate the area of rectangle 3
Area = (4.3)(2.25)
Area = 9.675 in²
4.- Calculate the total area
Area = 19.8 + 9.675 + 9.675
Area = 39.15 in²
Second way
Area 1 = 2[6.55 x 2.25]
Area 1 = 29.475 in²
Area 2 = (8.8 - 2.25 - 2.25)(6.55 - 4.3)
Area 2 = 4.3 x 2.25
Area 2 = 9.675 in²
Total area = 29.475 + 9.675
= 39.15 in²
Third way
Area 1 = (8.8 - 2.25)(6.55 - 4.3)
= (6.55)(2.25)
= 14.7375 in²
Area 2 = (4.3)(2.25)
= 9.675 in²
Area 3 = (6.55)(2.25)
= 14.7375 in²
Total area = 14.7375 + 9.675 + 14.7375
= 39.15 in²

Answer:
The surface area of right regular hexagonal pyramid = 82.222 cm³
Step-by-step explanation:
Given as , for regular hexagonal pyramid :
The of base side = 3 cm
The slant heights = 6 cm
Now ,
The surface area of right regular hexagonal pyramid =
Where a is the base side
And h is the slant height
So, The surface area of right regular hexagonal pyramid =
Or, The surface area of right regular hexagonal pyramid =
Or, The surface area of right regular hexagonal pyramid = 23.38 + 9 ×
∴ The surface area of right regular hexagonal pyramid = 23.38 + 9 × 6.538
I.e The surface area of right regular hexagonal pyramid = 23.38 + 58.842
So, The surface area of right regular hexagonal pyramid = 82.222 cm³ Answer
