I can type 19 words in 38 seconds. How many can I type in 60 seconds?

mel-nik [20]

Hi!

We can solve this by setting up a proportion

$\frac{19}{38} \frac{x}{60}$

Solve for x by cross multiplying.

19 x 60 = 1140
1140/38 = 30

You can type 30 words in 60 seconds

Hope this helps! :)

What is the surface area of the ice cream

galina1969 [7]

Answer:

$13194.7\ mm^2$

Step-by-step explanation:

The total surface area of a cone is given by:

Surface area = $\pi r(r+\sqrt{h^2+r^2} )$

where r is the radius of the cone, h is the height of the cone, l is the length of the cone = $\sqrt{h^2+r^2}$

Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:

$Surface \ area=\pi r(\sqrt{h^2+r^2} )=\pi rl\\\\Surface \ area=\pi (30\ mm)(140\ mm)=13194.7\ mm^2$
