Answer:
Step-by-step explanation:
It is given that A pyramid has a rectangular base with edges of length 10 and 24. The vertex of the pyramid is directly 13 units above the center of the base.. then The total surface area = area of rectangular base + area of 2 isosceles triangles with a base of 24 units + area of 2 isosceles triangles with a base of 10 units.
Area of rectangular base =
The slant height of isosceles triangles with a base of 24 units =.
The area of 2 isosceles triangles with a base of 24 units=
The slant height of isosceles triangles with a base of 10 units =
The area of 2 isosceles triangles with a base of 10 units=
The total surface area of the pyramid = 240 + 334.281 + 176.918 = 591.97 sq units.
Answer:
Step-by-step explanation:
4x + 3 + 2x + 21 = 180
6x + 24 = 180
6x = 156
x = 26
4(26) + 3 = 107
2(26) + 21 = 73
Answer:
If you plot these points you will see that the base is 6 (distance from E to F, count the squares).
The height will be 6 ( distance from line EF to D, again count the squares).
Using the Area formula you get A = 1/2 (6) (6) = 18
Answer:
For this equation let's round the 3328 to a 3300.
Step-by-step explanation:
If we remove the 2 zeros, we remain with a 33. 33/6 is 5.5 Now if we add back 2 places we get 550. I know this is written badly, but I hope it helped.
The cost of the utility pole is $707. 32

How to determine the volume</h3>
From the information given, we have the following deductions:
- Density = 7.6 g/cm³
- Mass = Ikg = 1000g
- Cost per mass = $0. 51
Let's determine the volume of this cylinder:
Volume = mass / density
Substitute the values
Volume =
Volume = 131. 58 cm³
Thus, 131. 58 cm³ costs $0. 51
For the utility pole;
Volume = 2 πr²h
Where:
- r is 8. 8cm
- height is 750cm
Volume = 3. 142 × 8. 8 × 8. 8 × 750
Volume = 182, 487. 36 cm³
If 131. 58 cm³ costs $0. 51
Then 182, 487. 36 cm³ will cost:
= 182, 487. 36 × 0. 51/ 131. 58
= 93068. 55/ 131. 58
= $707. 32
Thus, the cost of a utility pole is $707. 32
