1) What is the slant height x of this square pyramid? Express your answer in radical form
sin 60=x/4--------> x=4*sin 60------> 4*(√3/2)-------> 2 √3 m
the answer Part 1) is 2 √3 m
2) The base of a regular pyramid is a hexagon. What is the area of the base of the pyramid?
[area of the base}=[area of hexagon]
[area of hexagon]=6*[area of triangle]
area of triangle
sin 60=a/14-------> a=(√3/2)*14-------> a=7√3 cm
cos 60=(b/2)/14--------> (b/2)=cos 60*14-----> (1/2)*14---------> (b/2)=7
base of triangle=2*7--------> b=14 cm
[area of triangle]=14*7√3 /2--------> 49√3 cm²
so
[area of hexagon]=6*[49√3]--------> 294√3 cm²
Answer:
15,15,15,
Step-by-step explanation:
48=12+12+12+12
48=(12+3)+(12+3)+(12+3)+(12+3)
Answer:
8 1
/2
For this we need to determine what
2
/3 of 12 3/4 is, so we multiply the fractions together.
The answer is 1/12
The chance of getting a 3 on a six-sided dice is 1/6
The possibility of getting heads on a two-sided coin is 1/2
6 multiplied by 2 is 12
1 multiplied by 1 is 1
Hope it helps!
