Explanation:

Question 1

Step1: Recall circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \), where \( d \) is the diameter. So we need to multiply the diameter (1700 feet) by \( \pi \) (approximately 3.14). So the operation needed is multiplication.

An acute angle is an angle that measures less than 90 degrees. The given angle in the diagram appears to be less than 90 degrees, so it is an acute angle.

Step1: Define opposite number

The opposite of a number \( a \) is \( -a \). So for \( - 37 \), the opposite is \( -(-37) \).

Step2: Simplify the expression

\( -(-37)=37 \) (since the negative of a negative number is positive).

Answer:

Multiplication (using \( C = \pi d \), so multiply diameter by \( \pi \))
