Answer:
becauz the cos .1sj sin A the thing cos
No I do not agree with (2,-4) I believe the solution is (-4,2)
Answer: $2.50
for rounding to the tenths, look at the hundredths place and if it is more than 5 round up :)
Volume for a cone is 1/3 pi * r^2*h, where r is radius and h is height. We have diameter = 1/2 radius. Thus, radius = 1.5in. We also have volume is 12 in. Using formula for volume of a cone and plugging in what we know, we have 12 = 1/3*pi*(1.5)^2*h, were solving for h. To get, h= (12*3)/(pi*(1.5)^2), which is approximately 5.0931in, 5 inches
3 x 4 is equal to 12 I think that’s your answer
