Mathematics

Evgen [1.6K]3 years ago
4 0
The circumference formula is 2Πr, so simply equal that formula to 75.
2Πr=75
Divide both sides by 2
Πr=37.5
So radius is 37.5/Π.

A clock tower has a circular clock face with an area of 144pi square feet. What is the diameter of the clock face? Teacher wants
nekit [7.7K]

Answer:

d = 24

Step-by-step explanation:

The area of a circle is given by A = π * r²

We are told the area of the clock is 144π.

Let's clear the formula for the radius:

r² = A / π

r² = 144π / π

r² = 144

r = √144

r = 12

The diameter is two times the radius, d = 2r = 2*12 = 24.
