Answer:
1/2
Step-by-step explanation:
The hypotenuse is approximately 6.2
Since -(9/16) is a negative number, it has no real square root. The square root of a negative number is usually represented by an imaginary number. Therefore, the answer to the question is OPTION D (No Real Root)
Answers:
- Lateral Area = No lateral area (choice D)
- Surface Area = 25.97 square inches (choice E)
- Volume = 12.44 cubic inches (choice A)
============================================
Explanation:
Lateral area only applies to prisms and cylinders. Spheres do not have lateral sides, so there is no lateral area.
-----------------------
The radius is 1 & 7/16
Let's convert this to decimal form
1 & 7/16 = 1 + (7/16)
1 & 7/16 = 1 + 0.4375
1 & 7/16 = 1.4375
The radius is r = 1.4375 inches.
-----------------------
SA = Surface area the sphere
SA = 4*pi*r^2
SA = 4*pi*(1.4375)^2
SA = 25.9672267773281
SA = 25.97 square inches (choice E)
-----------------------
V = Volume of the sphere
V = (4/3)*pi*r^3
V = (4/3)*pi*(1.4375)^3
V = 12.4426294974698
V = 12.44 cubic inches (choice A)
So, the formula is length times width divided by 2
so multiply 12 and 9
12*9 = 108
divide 108 by 2
108/2 = 54
That formula ONLY WORKS ON TRIANGLES
