Answer:
4.835(I don't know unit.(m/in/cm)
Step-by-step explanation:
volume=πr^2h
136.78=22÷7×3^2×h
h=136.78×7÷(22×9)=4.835
10x and 2x is the answer to your question then do the equation
Answer:
h(g(x))=h(3x^2+1)=2(3x^2+1)=6x^2+2
Using the pythagoras theorem
side = sqrt (61^2 - 11^2) = sqrt 3600 = 60 in Answer
