The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.
The area can be calculated in terms of known linear measurements of the circle:
-- Area = (π) x (radius)²
-- Area = (π/4) x (diameter)²
-- Area = (1/2) x (circumference) x (radius)
-- Area = (1/4) x (circumference) x (diameter)
Any of these formulas will give you the area. The one you decide to use
just depends on what you already know about the circle.
Answer:
A and B: Isosceles (having two sides of equal length)
C: Equilateral (all sides are equal)
Answer:
by dividing 6,400 by 2,000
Step-by-step explanation:
We know that 2000 pounds equals 1 ton
To convert 6400 pounds to tons, we need to
6400 pounds * 1 ton/2000 pounds
Divide 6400 by 2000
Answer:
Step-by-step explanation:
1.14, just like 114%
Answer:
229.5
Step-by-step explanation:
In order to calculate the area of the arrow we need to calculate the area of the body of the arrow, and then the head of the arrow. The body of the arrow is a rectangle meaning that the area (Ar) can be calculated by multiplying the length by the height like so...
Ar = l * h
Ar = 11cm * 12cm
Ar = 132
Now we need to find the area of the head of the arrow, which is a triangle and therefore we can use the formula for the area of a triangle (At) which is height times base divided by 2...
At = 
At = 
At = 
At = 97.5
Now we simply add both areas together to calculate the total area of the arrow...
132 + 97.5 = 229.5
