I don’t know what is the math
Answer: <u><em>Diameter = 10cm</em></u>
<u><em>Circumference = 31.4cm</em></u>
<u><em>Area = 78.57cm2</em></u>
Step-by-step explanation: Radius = 5cm
→Diameter = 2×radius
= 2×5 = 10cm
Diameter = 10cm
→ Circumference = 2 ×22/7 × 5
= 220/7
=31.4cm
→ Area = 22/7 × 5 × 5
22/7× 25 = 78.57cm2
553 because you just add those two numbers together
Answer:
Step-by-step explanation:
A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.
In the unit circle below, we can see that the line touches the unit circle at point 
, therefore to find the tangent of theta, we use the formula:
We have 89 ounces of 47% iodine.
We will add "x" ounces of 14% iodine to get a 29% iodine solution.
89 * .47 + .14x = .29 * (89 + x)
41.83 + .14x = 25.81 + .29x
16.02 = .15x
x = 106.80
So, we must add 106.80 ounces of 14% iodine to get a 29% iodine solution.
(for a total of 195.80 ounces)
