Brenda wants to attatch a string of beads along the circular bottom edge of a lamp shade shown below. The diameter of the bottomof the lamp shade is 18 centimeters. About how many centimeters long should Brenda make the string of beads?
a.25 cm
b.79 cm
c.56 cm
d.201 cm
It is asking for circumfrence. Diamiter is half of the circle. So you need to multiply 18 by PI and you get your answer.
jenna has a paper route .she delivers papers to 30 customers .at the end of the month she gets $6.50 from each customer.she pays the newspaper company $135 each month for the newspaper.
To determine the length of the string of beads that Brenda needs, we need to calculate the circumference of the circular bottom edge of the lamp shade.
The circumference of a circle is calculated using the formula: C = π * d
Given that the diameter of the lamp shade's bottom is 18 centimeters, we can substitute this value into the formula to find the circumference.
C = π * 18 cm
To solve this problem, we need to approximate the value of π. Let's use 3.14 as a reasonable approximation.
C ≈ 3.14 * 18 cm
C ≈ 56.52 cm
Therefore, Brenda should make the string of beads approximately 56 centimeters long.
The correct answer is c. 56 cm.
