In an hour the minute hand goes all the way around, or a 360 loop. so it's its $\pi$ times the radius squared.

To find slope subtract the two points in the coordinate (y). We have 8 and 4 so subtract those two. You get 8-4=4. Now start from the same coordinate expect this time subtract (x). Which is 9-3=6. You have 4/6 simplify and you get 2/3. Your slope is 2/3. Hope this helps

17/13 = y/10 solve for y and round to the nearest tenth

11Alexandr11 [23.1K]

$\frac{17}{13} = \frac{y}{10}$

$17 \times 10 = y \times 13$

$170 = 13y$

$y = \frac{170}{3} = 56.6666....$

56.6666... to the nearest tenth is <u>57</u>.

The radius of a cylindrical gift box is (2x+3) in. The height of the gift box is twice the radius. What is the surface area of t

inessss [21]

SA=2pir^2+2hpir=2pir(r+h)
h=2r=2(2x+3)=4x+6

SA=2pi(2x+3)(2x+3+4x+6)
SA=(4x+6)(pi)(6x+9)
SA=24πx²+27πx+54π
