Answer:
17.1972degrees
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Substitute the given angle;
1.2 = theta/360 * 2(3.14)(4)
1.2 = theta/360 * 25.12
1.2/25.12 = theta/360
0.04777 = theta/360
theta = 360 * .04777
theta = 17.1972
Hence the required angle is 17.1972degrees
The volume equation for a cylinder is V=(pi)(di^2)(h)/4, so in this problem it is V=pi(8^2)(10)/4 --> V=pi(64)(10)/4 --> V=pi(640)/4 --> V=160pi or 502.65

Answer:
Sin A = 15 / 17
Step-by-step explanation:
Given a right angled triangle, we are to obtain the Sin of the angle A ;
Using trigonometry, the sin of the angle A, Sin A is the ratio of the angle opposite A to the hypotenus of the right angle triangle.
Hence. Sin A = opposite / hypotenus
Opposite = 15 ; hypotenus = 17
Sin A = 15 / 17
Well I believe in question 12, that the shape has 4 sides, 4 right angles, its a parallelogram, its a quadrilateral, and its a shape. Is that what it means by classify?
