Answer:
452.2 cm
Step-by-step explanation:
A = 4πr²
A = 4 (3.14) (6)²
A = 4 (3.14) (36)
A = 452.16
A = 452.2 cm (nearest tenth)
Just do 300x1.4 because that gives you the extra 40% (the answer is £420 btws)
Answer:
The center is the point (3,1) and the radius is 3 units
Step-by-step explanation:
we know that
The equation of a circle in standard form is equal to
we have
Convert to standard form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
The center is the point (3,1) and the radius is 3 units
Answer:
scale = 14.5 cm perimeter
actual = 29 inch perimeter
Step-by-step explanation:
To find the perimeter of the scale drawing, we can just add up the scale sides.
This would be 2.5 + 2.5 + 4.75 + 4.75 = 14.5 cm perimeter
For the real flag, we know that for each cm on the scale flag, it represents 1 inch on the actual flag.
2.5/.5 = 5 inch length
4.75 / .5 = 9.5 inch width
5 + 5 + 9.5 + 9.5 = 29 inch perimeter
