Answer:
SA = π3^2 + π3(7.5)
Step-by-step explanation: r is radius and L
is r*l/2
so 3*5/2=15/2=7.5
seriously look at a problem more carefully and memorise your formulas!
what is the question? Please ask a question.
this is an isosceles triangle... meaning that the two base angles will be equal.
180 - 38 = 142
142 / 2 = 71
x = 71
