Answer:
To the first question the answer would be > because you can change -3/4 to -9/12. Since these are negative numbers -5 is greater than -9.
The answer the second one would be B because I change all the fractions to decimals and 6/11 equals 0.54545454 and goes on and on So it was the greatest number (in decimal form). Also negaitve numbers are the least. :) Hope this helps
Step-by-step explanation:
Volume = Length x Width x Height
Volume = 8 x 5 x 2 = 80 in³
Answer: 80 in³
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
