Answer:
a. d = C/π
b. d = 8/π inches ≈ 2.546 inches
c. r = 61/(2π) inches ≈ 9.708 inches
Step-by-step explanation:
a. The formula for circumference is ...
C = πd
Dividing by π gives ...
d = C/π
__
b. For a circumference of 8 inches, the diameter is ...
d = (8 in)/π = (8/π) in ≈ 2.546 in
__
c. The radius is 1/2 the diameter. So, the radius of a circle is ...
r = d/2 = (C/π)/2 = C/(2π)
For a circumference of 61 inches, the radius is ...
r = (61 in)/(2π) = 61/(2π) in ≈ 9.708 in
Answer:
Step-by-step explanation:
A = LW + ½πr²
A = 15(12) + ½(3.14)(12²/4)
A = 180 + 56.52
A = 236.52 m²
3/4 * 2 1/2 = 3/4 * (5/2) = 15/8 = 1 7/8
Answer:
4200 with 35% markdown: 2730
5000 with 44% markdown: 2800
Step-by-step explanation:
To calculate the price of an item including the markdown, multiply the original price by (1 minus markdown).
Convert the markdown percentage to decimal form before subtracting.
4200 with a 35% markdown: (35% = 0.35)
4200*(1 - 0.35)
= 4200 *(0.65)
= 2730
5000 with a 44% markdown: (44% = 0.44)
5000*(1 - 0.44)
= 5000*(0.56)
= 2800
Therefore, the sale price for $4200 with a 35% markdown is $2730, and the sale price for $5000 with a 44% markdown is $2800.
