To solve for k, you will need to use the circumference formula and what you know about circles. The distance around this figure would consist of one full circumference (all 3 circular sides put together) and one diameter (the 2 straight edges together).
97.29 = pi x d + d
97.29 = 3.14d + d: combine your like terms
97.29 = 4.14d; divide both sides by 4.14
d = 23.5 inches
k is the distance of the diameter, so k = 23.5 inches.
Answer:
a = -0.8b
Step-by-step explanation:
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4b' to each side of the equation.
5a + 4b + -4b = 0 + -4b
Combine like terms: 4b + -4b = 0
5a + 0 = 0 + -4b
5a = 0 + -4b
Remove the zero:
5a = -4b
Divide each side by '5'.
a = -0.8b
Simplifying
a = -0.8b
4 1/3 x 3 x 1 ¼
12 ¾ x 3 x 1 1/4
Your lucky that I just had the question on a test and realized you didn't make it into fractions.
