Find the surface area of a 7.4 cm long iron rod and 3.1 m radius

Debora [2.8K]

Answer:

144.2 cm

Step-by-step explanation:

Length of the iron rod is 7.4cm

Radius is 3.1m

Therefore the surface area can be calculated as follows

= 2πrl

= 2×3.142×3.1×7.4

= 144.2 I'm

Hence the surface area is 144.2cm

In this triangle, what is the value of x?

nalin [4]

Answer: $x=56.5\ km$

Step-by-step explanation:

Given the right triangle in the image, you need to remember the following identity:

$cos\alpha=\frac{adjacent}{hypotenuse}$

Observe the triangle. You can identify that:

$\alpha=28\°\\adjacent=x\\hypotenuse=64$

Then, knowing these values, you can substitute them into $cos\alpha=\frac{adjacent}{hypotenuse}$ :

$cos(28\°)=\frac{x}{64}$

Finally, you have to solve for "x".

Therefore, the value of "x" rounded to the nearest tenth is:

$64*cos(28\°)=x\\x=56.5\ km$

It would be D because the equation just seems flipped, but the requirements of x are fulfilled.

The answer is C

you would isolate x in the first equation then substitute it in to the second equation and solve for y. then plug y in to the first equation.
