I just had this question choose "d" hope it helps
Answer:
56.25 cm
Step-by-step explanation:
your teacher wrote the approach already : the law of sines.
in our example we have
sin(28)/27 = sin(102)/c
c×sin(28)/27 = sin(102)
c×sin(28) = 27×sin(102)
c = 27×sin(102)/sin(28) = 27×0.98/0.47 = 56.25 cm
Answer:
x=−2 or x=5
Step-by-step explanation:
Answer:
<u>Given</u>
a.
<u>Volume of the half-sphere:</u>
- V/2 = 1/2*4/3*πr³ = 2/3*3.14*1.6³ = 8.6 cm³ (rounded)
b.
<u>Volume of the cylinder:</u>
- V = πr²h = 3.14*1.6²*6.2 = 49.8 cm³
c.
<u>Volume of the figure:</u>
- V = 8.6 + 49.8 = 58.4 cm³
