-2/3 times -2. You change -2 into -2/1 so you can multiply numerator to numerator and denominator to denominator. You will get 4/3 (negatives cancel out)
Answer:
18
Step-by-step explanation:
this is the surface area but what is the question
Answer:
X,Z,Y
Step-by-step explanation:
9π=28.27
√3/2=0.866
z=27.5
remember all are in cm^2 so no conversion is needed
The answer you chose is correct. You should make sure that you check both of your intercepts before coming to a conclusion and determining your answer.
Hoped I helped!
H = 10 cm, a - edge;
V = 1/3 a²√3 / 4 * h
h² = ( 2/3 * a√3 / 2 )² + a²
100 = a²/3 + a²
100 = 4 a² / 3
a² = 75
a = √75
a = 5 √3 cm
V = 1/2 * 75√3 / 4 * 10 = 250√3 / 4 = 62.5√3 cm³ ≈ 108.25 cm³
