Question

Okay I just need someone to check my work because the site I do school on is telling me that my answer is wrong. Here is the question:
Find the lateral area, total area, and volume for the cylinder with the given measurement.

r = 1, h = 1

Hereis my work:
LA= 2pirh
LA=2pi(1)(1)
LA=2pi(2)
LA=4pi

TA=2pirh+2pir*2
TA=4pi+2pi(1)*2
TA=4pi+2pi(1)
TA=4pi+2pi
TA=6pi

V=pir*2h
V=pi(1)*2(1)
V=pi(1)(1)
V-2pi

What am I doing worng!?! :(

Answer 1

The volume is \[\pi\cdot r^2 \cdot h\]

Answer 2

I have the formula and the answer I got was 2piis this wrong???

Answer 3

If r is 1 and h is 1, than\[\pi \cdot r^2 \cdot h = \pi \cdot 1^2 \cdot 1 = \pi \cdot 1 \cdot 1 = \pi\]

Answer 4

you did r*2 not r squared

Answer 5

for LA you made 1*1 = 2 ?

Answer 6

V=3.14(r)squared(h)
V=3.14(1)squared(1)
V=3.14(1)(1)
V=2pi

Answer 7

I used the* sign as my square sign! I am sorry I did not tell U guys!!

Answer 8

\[1\cdot1\neq2\]\[1\cdot1=1\]

Answer 9

\[\pi \cdot 1 \cdot 1 \neq2 \pi\]\[\pi \cdot 1 \cdot 1 = \pi\]

Answer 10

THANK YOU!! I understand what I was doing wrong now!!
