Answer:

183.17 cm cubed

Step-by-step explanation:

You would multiply 1/3 times pi times the radius squared times the height

so it would look like 1/3 * 3.14 * 5 squared * 7

5 squared is 25 and 25 times 7 is 175

Then you multiply 175 by 3.14 giving you 549.5

then you divide 549.5 by 3 resulting in 183.1667

then you round to 183.17 cm cubed

Find the length of the lamppost to the nearest inch.

olganol [36]

Answer:

109 inch

Step-by-step explanation:

we know that

$tan\theta=\frac{Perp}{Base} \\\theta=70\\Base=40 in$

So,

$tan(70)=\frac{Perp}{40} \\\\2.747=\frac{Perp}{40} \\\\2.747\times40=Perp\\\\Perp=109\quad in$

So, length of lamppost is 109 inch

Answer:

9.70 seconds

Step-by-step explanation:

The zero of the equation can be found using the quadratic formula.

ax² +bx +c = 0

x = (-b ±√(b² -4ac))/(2a)

We are only interested in the positive value of x, so this will be ...

x = (-147 -√(147² -4(-16)(80)))/(2(-16)) = (147 +√2679)/32

x ≈ 9.7028 ≈ 9.70 . . . . seconds

The rocket will hit the ground after about 9.70 seconds.
