Surface = 2 x PI x r x H + 2 x PI x r^2
= 2 x r x h + 2 x r^2
= 2 x 6 x 12 + 2 x 6^2
= 144 + 72
= 216 PI in^2
Answer is A
<h3>The measure of angles of triangle are 96 degree, 36 degree and 48 degrees</h3>
<em><u>Solution:</u></em>
The ratio of the measures of the angles in a triangle is 8:3:4
Let the first angle be 8x
Let the second angle be 3x
Let the third angle be 4x
We know that,
sum of all angles in triangle is 180 degrees
Therefore,
8x + 3x + 4x = 180
15x = 180
x = 12
Thus,
First angle = 8x = 8(12) = 96
second angle = 3x = 3(12) = 36
third angle = 4x = 4(12) = 48
Thus measure of angles of triangle are 96 degree, 36 degree and 48 degrees
