For this question you must know about 45 45 90 triangles and 30 60 90 triangles and their special properties first you have to find the hypotenuse of the 45 45 90 triangles which is always square root of two times a leg in this case 10. so now you have 10squareroot2 the longer leg is sqare root 3 times the shorter leg in a 30 60 90 triangle
x=10squareroot6
and y is 2 2 times larger than the shorter side
y=20squareroot3
The answer will be 24m^2
because you have to find the area first so : Length * width.
which equals 4. and then you multiply it by 6
because cube is made up of 6 perfect squares.
Answer:
B. 140π units²
Step-by-step explanation:
Surface area of a cylinder:
2πrh + 2πr²
2π(5)(9) + 2π(5²)
90π + 50π
140π
