Answer: 340 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Circumference = 2π radius
Replacing with the circumference value and solving for r:
31.416 =2π r
31.416 /2π =r
5cm =r
And then:
Volume of a cone = 1/3 x π x radius^2 x height
Replacing with the values given:
V = 1/3 π (5)^2 (13) = 340 cm3
Feel free to ask for more if needed or if you did not understand something.
Answer:
The length of side x is 22.91
Step-by-step explanation:
As per law of cosine
Where
degrees
a = 20
b = 27
Substituting the given values in above equation, we get -
Hence, the length of side x is 22.91
The correct answer for this is shown below in the picture
