Answer:
As a decimal its 6.34, If you round up then its 6.35
As a fraction its 400/63
As a mixed number its 6 22/63
The surface area of cylinder is 8.625 , if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Step-by-step explanation:
The given is,
Cylinder has a 5 centimeters height
Diameter of the cylinder is 1.5 centimeters
Step:1
Formula for the surface area of cylinder is,
......................................(1)
Where,
h - Height of cylinder
r - Radius of cylinder
From the values of h and r,
=
r = 0.75 cm
From the formula,
= ( 2 × × 0.75 × 5 ) + ( 2 × × )
= ( 7.5 ) + ( 1.125 )
A = 8.625
Result:
The surface area of cylinder is 8.625 , if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess

Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).
Hence, the rotational speed is 0.38 rotation per second.
