The circular base of a cone has a radius of 5 centimeters. The height of the cone is 12 centimeters, and the slant height is 13
Iteru [2.4K]

Answer:

283 cm^2

Step-by-step explanation:

Solution:-

We have a cone with a circular base of radius r = 5 cm

The height of the cone is h = 12 cm

The slant height of the cone is L = 13 cm

We are to determine the surface area of the cone. The surface area of the cone is comprised of two parts:

         Base Area : Circle

               A_1 = \pi r^2\\\\A_1 = \pi 5^2\\\\A_1 = 25\pi

        Curved Surface: conical

                A_2 = \pi * r*L\\\\A_2 = \pi * 5*13\\\\A_2 = 65\pi

The total surface area of the cone can be written as ( A ):

               A = A_1 + A_2\\\\A = (25 + 65 )*\pi \\\\A = 90*(3.14) \\\\A = 282.7433 cm^2

Answer: The surface area of the cone to nearest whole number would be 283 cm^2

Write 0.46 as a fraction in simplest form
butalik [34]
Here's how to convert 0.46 to a fraction...

There is not much that can be done to figure out how to write 0.46 as a fraction, except to literally use what the decimal portion of your number, the .46, means.

Since there are 2 digits in 46, the very last digit is the "100th" decimal place.

So we can just say that .46 is the same as 46/100. The fraction is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 46 and 100.
So, this fraction reduced to lowest terms is 23/50

So your final answer is: 0.46 can be written as the fraction 23/50
