It would be 5sqrt2

a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25 + 25 = c^2
50 = c^2
c = sqrt 50
c = 5sqrt2

The formula for area is pi x r^2 (pi times radius squared) so, for number 7 youre given the radius or "r", which is half the length of the inside of the cirlce. On a calculator: you would do 8 times 8 (8^2) because that's the radius squared and then you should get 64 and times 64 by 3.14 or use the pi button depending on what your teacher prefers you to use. 

When you're given diameter or "d" which represents the is equal to the radius times 2. So, for example, number 8 the diameter is 26 so, the radius is 13. Use the formula for area just like in number 7 to find the area of this circle. 

Make sure you pay attention to what information youre given (whether its "d", Diameter, "r" or radius. Use those two lists of steps for solving numbers 7 through 12. 

For numbers 13-15:
use the number (22/7) instead of 3.14 or the pi button on your calculator and do the same steps!!!!!

Let me know if you still need help after this:) happy math solving!

Suppose y varies directly with x write a direct variation equation that relates x and y
gogolik [260]

Answer:

Option D

Y=2.6x

Step-by-step explanation:

When y=10.4 and x=4, these two can be related by the equation

10.4=4x

Making x the subject of the formula then x=10.4/4=2.6

Relating x and y then we have the equation

Y=2.6x

For example, when x is 4 then y=2.6x=2.6(4)=10.4 as given in the question. Therefore, the right option is D

Y=2.6x
