Oh dear, this is so troll but acting oblivious is probably what I would do, and if action is taken, well...run xD
Answer:
- 24 cm²
- 6400 -1600π ≈ 1373.45 square units
Step-by-step explanation:
1. You can look at this several ways.
It can be considered to be a stack of 1+2+3 = 6 squares that are 2 cm on a side, so have a total area of 6 × (2 cm)² = 24 cm².
You can lop off one of the squares sticking out and put it into the empty corner to form a 6 cm by 4 cm rectangle with an area of (6 cm)(4 cm) = 24 cm².
You can consider it to be a 6 cm square with 3 squares cut out of it that are 2 cm on a side: (6 cm)² -3(2 cm)² = (36 -12) cm² = 24 cm².

2. The shaded area is the difference in areas of a square 80 units on a side and a circle of 40 units radius. If we let d represent the side dimension of the square, then the area formulas are ...
Square area = d²
Circle area = π(d/2)²
So the difference area is ...
shaded area = d² -(π/4)d² = d²(1 -π/4)
For d=80, the shaded area is ...
shaded area = 80²(1 -π/4) = 6400 -1600π ≈ 1373.45 square units
** where "r" is radius and "h" is height **
as it refers to the volume of cone being 1/3 of the the volume of cylinder
Hardest, example:
given height of cone is 69 km and radius is 48 km
using the formula:
Answer:
B
Step-by-step explanation:
An object on the moon weighs 1/6th of its weight on earth. If the object weighs 12 lbs then it weighs 1/6(12) = 12/6 = 2 lbs. This can be applied to any object's weight using m = e/6.
The answer would be -9
I hope this helps.
