Answer:
Step-by-step explanation:
A=2*pi*r*h+2*pi*r*2
A=(2*pi*2*8)+(2*pi*2*2)
A=125.66
To express the answer in terms of Pi
A=125.66/pi (3.14)
A=40 pi
Answer:
Step-by-step explanation: The surface area formula for a cylinder is
A=2*π*r*h+2*π*r^2
This picture gives us the radius, which is 2cm, and it gives us the height which is 8cm.
All we have to do now is just plug in the two numbers.
A= 2πrh+2πr^2
A=2π*2*8 + 2π*4
A=4π*8+8π
A=32π+8π
A=40πcm
The answer is 40π cm then!

Answer:
2, 1, 1/2, 1/4
Step-by-step explanation:
2¹ = 2
2^0 = 1
2^-¹
= 1/2¹
= 1/2
2^-2
= 1/2²
= 1/2*2
= 1/4
To complete the table
2² 2¹ 2^0 2^-1 2^-2
4 2 1 1/2 1/4
