Answer:
<u>341 cm²</u>
Step-by-step explanation:
Formula :
<u>Surface area = Area of 4 triangle faces + Area of square base</u>
<u />
===============================================================
Solving :
⇒ Surface area = 4 × 1/2 × 11 × 10 + 11²
⇒ Surface area = 2 × 110 + 121
⇒ Surface area = 220 + 121
⇒ Surface area = <u>341 cm²</u>

Answer:
The size of the sample is 23 scientists.
Answer:
b = 9 ft
Step-by-step explanation:
Pythagorean Theorem:
a^2 + b ^2 = c^2
Given:
a = 12
b = ?
c = 15
Plug in values:
12^2 + b^2 = 12^2
Solve for b^2:
b^2 = 15^2 - 12^2
b^2 = 225 - 144
b^2 = 81
Take square root of both sides to find b:
sqrt(b^2) = sqrt(81)
b = 9
