A clock has a pendulum 22 cm long. If it swings through an angle of 32 degrees, how far does the bottom of the bob travel in one
swing?
1 answer:
Answer:
12.287 cm
Step-by-step explanation:
32 degrees = 32*(π/180)rad/degree = 0.5585 rad
The chord length that the bob sweeps equals to the product of chord angle and the swinging radius, aka pendulum length
= 0.5585 * 22 = 12.287 cm.
So the bob swings a distance of 12.287 cm at an angle of 32 degrees.

U're goal is to get k alone.
So divide both sides by 9/10.
3/2 divided by 9/10 is 5/3
9/100 is 9/100 in its simplest form.
You can also say that 9/100=0.09
The answer is
-10=-15+5x
x = 1
Answer:
C. 238π cm^3.
Step-by-step explanation:
Surface area = 2 * area of the circular ends + area of the curved length
= 2π r^2 + 2π r* l
= 2 π 7^2 + 2π 7 * 10
= 98π + 140π
= 238π cm^3.
Answer:
3.22
Step-by-step explanation:
You would multiply it normally than move one place behind the decimal.
