Step-by-step explanation:
The circumference of a DVD disc is 28.26 cm
Answer:
Option (A). 363 units²
Step-by-step explanation:
Surface area of the rectangular pyramid = Area of the rectangular base + Area of the lateral sides of the pyramid
Area of the rectangular base = Length × Width
= 11 × 11
= 121 units²
Area of the lateral sides = 4(Area of one lateral side)
= 4[]
= 2(11)(11)
= 242 square units
Area of the rectangular pyramid = 121 + 242
= 363 square units
Therefore, Option (A) will be the answer.
40 = 4 * 10
sqrt40 = sqrt2 * sqrt10
= 2 sqrt10
