The radius of the base of a cylinder is 28 cm and its height is 48 cm. Find the surface area of the cylinder in terms of π. 4,23
spin [16.1K]
\bf \textit{total surface area of a cylinder}\\\\&#10;SA=2\pi r(h+r)~~&#10;\begin{cases}&#10;r=radius\\&#10;h=height\\&#10;-----\\&#10;r=28\\&#10;h=48&#10;\end{cases}\implies SA=2\pi (28)(48+28)&#10;\\\\\\&#10;SA=56\pi (76)\implies SA=4256\pi

Tammy drove 871 miles in 13 hours.
Evgen [1.6K]

Answer:

Tammy takes 5 hours to drive 335 miles.

Step-by-step explanation:

Given that :-

  • Tammy drove 871 miles in 13 hours.

To find :-

How long would it take her to drive 335 miles ?

Solution :-

Let us assume that it take her to drive 335 miles in x hours.

To find x, we need to find it in ratios.

871 miles = 13 hours

335 miles = x hours

Using cross multiplication method

871 × x = 335 × 13

multiply to get

871 x = 4, 355

divide each side by 871

871 x / 871 = 4,355 / 871

x = 5

hence, Tammy takes 5 hours to drive 335 miles.

Suppose the graph of y= x^2 translated left 2 units, and up 8 units
Elis [28]

Start with y = x2

 

Shift 2 units left to get y = (x+2)2

 

Vertically stretch to get y = 6(x+2)2

 

Reflect across x-axis to get y = -6(x+2)2

 

Shift 7 units down to get y = -6(x+2)2 - 7

hope this helps!
