The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²

<h3>Surface area</h3>

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

where,

  • a = sides of base = 10 cm
  • h = slant height = 15 cm

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

= 10² + 2(10)√10²/4 + 15²

= 100 + 20√100/4 + 225

= 100 + 20√25 + 225

= 100 + 20√250

= 100 + 20(15.81)

= 100 + 316.2

= 416.2 cm²

Find the are of each figure
Umnica [9.8K]

Answer:

I think the figure of N and E of 48in is 2304. The figure of I and E and N and A of 32in is 1024. The figure of L and I and L and A is 144.

Step-by-step explanation:

To find the area, you have to multiply of each side in each figure. For example, Figure A and B and C and D of 16in is 16 × 16 which is 256.

A = Area

a = Side

A = 2304, A = a^2 = 48^2 = 2304.

A = 1024, A = a^2 = 32^2 = 1024.

A = 144, A = a^2 = 12^2 = 144.

I hope this answers your question!

Hello
hjlf

Answer:

1/10

Step-by-step explanation:

1 + 1/2 = 1 1/2

1 - 1/8 = 7/8

1 + 1/5 = 1 1/5

1 - 1/3 = 2/3

1 + 1/10 = 1 1/10

One and one tenth is closest to one because one tenth is the smallest amount that would need to be added or taken away to get exactly one. Hope I helped!
