surface area = 2 x pi x r x h + 2 x pi x r^2
2 x (3.14) x 1 x 12 = 75.36
2 x (3.14) x 1^2 = 6.28
75.36+6.28 = 81.64
if you cant use a fraction or decimal, does the answer need to be in terms of pi?
that would be 2 x PI x r x h = 2 x pi x 1 x 12 = 24PI
2 x PI x r^1 = 2 x PI x 1 = 2PI
24 PI x 2 PI = 26 PI
Hi! Sorry, it would've taken too long to type out, so I wrote it and have the attachment. Good luck!
Assuming you're trying to answer part B, there must be an image along with the question.
Answer:
210
Step-by-step explanation:
We can get 10% of 300 by doing 300 / 10 which is 30. 70 / 10 is 7, so we need 7 lots of 10% to work out 70%. Therefore, 30 * 7 students said that their favourite colour was blue, which is 210.
