Answer:
area = 779.4 cm²
Step-by-step explanation:
divide it into 6 equal equilateral triangles. Each corner of a triangle will be 60°.
tan 60° = 15/x
1.7321 = 15/x
x = 8.66 (this is one-half of the base of the triangle)
base = 17.32 cm
area of one triangle = 1/2(17.32)(15) = 129.9 cm²
129.9(6) = 779.4 cm² (because 6 triangles make up the hexagon)
Answer:
New can holds
more than the old can
Step-by-step explanation:
Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is 
Dimensions of the can are increased by a multiple of 1.10
To find: Difference between the volume of new can and volume of old can
Solution:
Volume of can (v) = 
Let r, h denote radius and height of the can.
Let R, H denotes radius and height of the new can.
r = diameter/2 = 
h = 12 cm
R = 
H = 
New volume (V) = 
So,

Answer:
500 childrens tickets
600 adults tickets
Step-by-step explanation:
$11.00 * 500 = 5,500
$36.00 * 600 = 21,600
21,600 + 500 = 27,100 tickets sold
