The circumference of a circle is 88cm. What is its radius?
A) 7cm
B) 9.8cm
C) 11cm
D) 14cm
Explanation: The formula to calculate the circumference of a circle is given by:
Circumference = 2π r
In this case, we are given the circumference as 88 cm. We can rearrange the formula to solve for the radius:
radius = Circumference / (2 × π)
Substituting the given circumference:
radius = 88 cm / (2 × 3.14159)
radius ≈ 88 cm / 6.28318
radius ≈ 14 cm

What is the solution of x + 5 = -2?
A) 7
B) -7
C) 10
D) -10
Explanation: To solve the equation
x + 5 = -2, we can isolate the variable x by subtracting 5 from both sides of the equation: x + 5 - 5 = -2 – 5
This simplifies to: x = -7
Therefore, the solution to the equation
x + 5 = -2 is B) -7.
