Transcript text: A baseball diamond is in the shape of a square with 80 ft sides. How far is it from home plate to second base? Give the exact value. Write the answer in simplest form. Then give an approximation to the nearest tenth of a foot.
Solution
Solution Steps
Step 1: Understand the Problem
The problem involves finding the distance from home plate to second base on a baseball diamond, which is a square with each side measuring 90 feet.
Step 2: Identify the Relevant Formula
To find the distance from home plate to second base, we need to calculate the diagonal of the square. The formula for the diagonal \(d\) of a square with side length \(s\) is:
\[ d = s\sqrt{2} \]
Step 3: Substitute the Given Values
Given that the side length \(s\) is 90 feet, substitute this value into the formula:
\[ d = 90\sqrt{2} \]
Step 4: Simplify the Expression
The exact value of the distance from home plate to second base is:
\[ d = 90\sqrt{2} \text{ feet} \]
Step 5: Approximate the Distance
To approximate the distance to the nearest tenth of a foot, calculate the numerical value of \(90\sqrt{2}\):
\[ 90\sqrt{2} \approx 90 \times 1.414 \approx 127.3 \text{ feet} \]
Final Answer
The exact distance from home plate to second base is \(90\sqrt{2}\) feet. The approximate distance to the nearest tenth of a foot is 127.3 feet.
