5 The base of a juice glass is in the shape of a circle with a diameter of 5 centimeters. Which of the following is closest to the circumference of the base of the juice glass? (Use 3.14 for π.)
A 15.7cm
B 19.6 cm
C 31.4 cm
D 78.5 cm
so that would be 15.7
Recall that C = πd
so, just multiply the two values.
To find the circumference of the base of the juice glass, we need to first find the radius of the circle. The diameter of the circle is given as 5 centimeters, so the radius would be half of that, which is 2.5 centimeters.
Now, we can use the formula to calculate the circumference of a circle: C = 2πr, where C is the circumference and r is the radius.
Substituting the values, we get:
C = 2 * 3.14 * 2.5
C ≈ 15.7 cm
So, the closest answer to the circumference of the base of the juice glass is A) 15.7 cm.
