Answer:
The correct answer is first option. 204 m²
Step-by-step explanation:
Formula:-
Lateral surface area of square pyramid = 4 * area of triangle
<u>To find the slant height of triangle(l)</u>
l = √(6² + 6²) = 6√2
To find the area of triangle
Area = bh/2
b = 12 m
h = 6√2
Area = (12 * 6√2)/2 = 36√2
<u>To find the lateral surface area of Prism</u>
Lateral surface area of square pyramid = 4 * area of triangle
= 36√2 * 4 = 203.64 ≈ 204 m²
First answer is the correct option
18) (10)7d/10=35(10)
7d/7=350/7
d=50
21) 3/4 w=27
(4/3)3/4 w=27(4/3)
w=36

Answer:
396 : 2 * 2 * 3 * 3 * 11
Step-by-step explanation:
using long division of prime factors, you will end up with the following:
396 : 2 * 2 * 3 * 3 * 11
V=1/3(pi)(r)^2(h)
V=1/3(pi)(9)^2(15)
V=1/3(3.14)(81)(15)
Then multiply all numbers in parentheses:
3815.1/3=1271.7 cm^3

Answer:
Hi there!
Your answer is;
17/6 <em><u>OR</u></em> 2 & 5/6
Step-by-step explanation:
(-5+1)/6 - (-8+1)/2
First, simplify in parentheses!
-4/6 - -7/2
Next, change the symbol of 7/2 because two negatives make a positive!
-4/6 +7/2
Next, change the denominators so they both have the same
-4/6 + 7/2
× 3/3
-4/6 + 21/6
Simplify!
17/6
<u>OR</u>
2 & 5/6
Hope this helps
