Question

S=π (1.5) √((1.5)^2+(4)^2) how to you solve this to get the answer?

Answer 1

S=π 1.5 √(1.5^2+4^2) actually its like this

Answer 2

just break it into steps:
\[1.5^2 + 4^2\]
then sqrt it. then multiply it by 1.5 and then if you are looking for a decimal answer multiply in your \[\pi\]

Answer 3

I tried that but I keep getting the wrong answer? one time I got 4.6 then another time 0 and the answer is supposed to be 20.13n^2

Answer 4

Okay, what do you get when you plug in \[1.5^2\] and \[4^2\] and when you add them.

Answer 5

18.25

Answer 6

yeah, now whats the sqrt of that?

Answer 7

333.06

Answer 8

Err I meant the square root of 18.25\[\sqrt(18.25)\] not \[18.25^2\]

Answer 9

4.3

Answer 10

right, now take that times 1.5 and \[\pi\]

Answer 11

ok how would I write that Im not doing something write I came up with zero again

Answer 12

plug \[4.3* \pi *1.5 \]into your calculator

Answer 13

got 6.45\[\pi\]

Answer 14

which is correct, you could also use 3.14 * \[\pi\]

Answer 15

Ok Im confused then how do I get the 20.13n^2 answer
