Answer 2

Calculating the Dome's Diameter of St. Isaac's Cathedral

To calculate the diameter of the dome of St. Isaac's Cathedral, we can use the formula for the circumference of a circle, which is given by:

C = πd

Where: - C is the circumference - π is a constant approximately equal to 3.14159 - d is the diameter

Given that the circumference of the dome's base is 25.8 meters, we can use this information to calculate the diameter.

Calculation

Using the formula C = πd, we can solve for d:

25.8 = πd

To find the diameter, we can rearrange the formula to solve for d:

d = 25.8 / π

Let's calculate the value of d using the approximate value of π as 3.14159.

Solution

d ≈ 25.8 / 3.14159 ≈ 8.21 meters

So, the diameter of the dome's base is approximately 8.21 meters.

I hope this helps! If you have any other questions or need further assistance, feel free to ask.
