Answer:
No, it is not
Step-by-step explanation:
11.5 is the longest side, so it is most probably the hypotenuse
using the formula a²+ b² = c², lets input the numbers
5² + 7² = 11.5²
25 + 49 = 132.25
74 ≠ 132.25
So this is wrong

Answer:
Thus the surface area of this cylinder involving pie is:
ft²
or
ft²
Step-by-step explanation:
Given
radius = r = 10 ft
height = h = 15 ft
The surface area of a cylinder formula is:

substituting the value = r = 10 ft and h = 15 ft

ft²
Thus the surface area of this cylinder involving pie is:
ft²
or
ft²
Answer:
The second one
Step-by-step explanation:
2x5=10
Answer:
x = 10, y ≈ 11.2
Step-by-step explanation:
Hi there,
We can find the length x first since we are given the lengths of the other two sides of the bottom right triangle. In order to find the length of x, it is important to know the Pythagorean Theorem and the fact that x is the hypotenuse.
+
=
← Pythagorean Theorem
<u>To find x:</u>
+
= 
100 = 
c = 10
Therefore, the value of x is 10.
<u>To find y:</u>
We now know the length of two sides of the upper right triangle. The value of y can be found by using the theorem again.
+
= 
+ 100 = 225
= 125
a = 
a = 11.2 when rounded to the nearest tenth.
Therefore, the value of y is approximately 11.2.
Hope this explanation is useful. Cheers.
