Answer:
14.4 would be the answer hope this is helpful
Step-by-step explanation:
14.4/30= 48%
Answer: About 88 inches
=============================================
Explanation:
Find the circumference
C = pi*diameter
C = (22/7)*28
C = 88
The tire's circumference is approximately 88 inches. This is the perimeter or distance around the circle. As the bike moves forward one full rotation of the wheel, all of the wheel will touch the ground at some point. The bike will move about 88 inches forward when the wheel does one full rotation.
A good way to visualize this is to imagine cutting the tire so that you can unroll it to lay it out completely flat forming a straight line. This line will be roughly 88 inches long.
Sector area = (Central Angle (Degrees) / 360) * PI * radius^2
One way to solve this is that an angle of (PI/4) = 45 degrees.
45 degrees is one eighth of a circle.
Area of ENTIRE circle = PI*radius^2 = PI * 3^2 =

By applying the Tan trigonometric formula, the value of the tangent for angle A is equal to: A. 3√91/91.
<h3>How to find the value of the tangent for <A?</h3>
In order to determine the value of the tangent for <A, we would apply Pythagorean theorem:
AB² = AC² + BC²
40² = AC² + 12²
AC² = 1600 - 144
AC = √1456
AC = 4√91 in.
Now, we can determine the value of the tangent for <A by applying the Tan trigonometric formula:
TanA = Opp/Adj
TanA = BC/AC
TanA = 12/4√91
TanA = 3√91/91.
