Arc length = radius * central angle (radians)
central angle (radians)= arc length / radius
central angle (radians)= 60 / 15
central angle (radians)= 4 radians
sector area =(central angle / 2) * radius^2
sector area = (4 / 2) * 225
sector area = 450

Answer:
14 inches
Step-by-step explanation:
Using this information, we can form an equation.
Since there are 3 sides in a triangle, and each side increased by 6, that means that the perimeter increased by 18 inches. Down below, I did 3x because there are 3 sides in a triangle.
(This is the equation you'd want to do to get the answer)
3x + 3 * 6 = 60
Simplify:
3x + 18 = 60
Same to both sides
3x = 42
Isolate x:
x = 14

Answer:
The surface area of capsule is 235.5 mm².
Step-by-step explanation:
Given that,
Diameter = 5 mm
Total length = 15 mm
We need to calculate the radius of each hemisphere
Using formula of radius of hemisphere
We need to calculate the length of cylinder
Using formula of length
Length of cylinder = Total length of capsule-radius of left hemisphere- radius of right hemisphere
We need to calculate the surface area of capsule
Using formula of surface area of capsule
Put the value into the formula
Hence, The surface area of capsule is 235.5 mm².
55-46.75= 9.25
the sales discount is $9.25
