Answer:

9sqrd= 81

12sprd= 144

144+81= 225

\sqrt{225}= 15

so c=15

ps. use Pythagoras to help you.

Answer:

c=15

Step-by-step explanation:

You can use Pythagoras theorem to find the value of c

Formula to find the hypotenuse:

c=\sqrt{a^{2}+b^{2}  }

The value of a in the formula will be the height & the value for b in the formula is the base.

Now, add the values in the formula:

c=\sqrt{9^{2}+12^{2}  }

c=\sqrt{81+144 }

c=\sqrt{225}

c=15.96871942

You can simply say that:

c=15

I hope this helps :)

What percentage of 80 is 40
SCORPION-xisa [38]

Let's do it this way.

80 is equal to 100% and we're trying to figure out what percentage would 40 be.

40 is half of 80. If you add 40 and 40 you'd get 80. So now that we know 40 is half of 80 we just need to figure out what percentage would be half of the whole (the whole is 100%)

So 100 split in half is 50.

So 40 would be 50% of 80.


I hope this helps :)

If you need anything else please message me.

Diameter = 18 cm
miskamm [114]

Answer:   B. 254.34 cm^2

Step-by-step explanation:

The area of a circle is pi times the radius squared.

Using the diameter we have to find the radius.

The diameter is two times the radius meaning that the radius is half the diameter.

18/ 2 = 9

The radius will be 9 cm

Now using the formula   v= pi * r^2    ,  input the value for pie and the radius and solve for  v  the volume

v = 3.14 * 9^2

v= 3.14 * 81

v = 254.34 cm^2
