Area of circle = Pi x r*2
If diameter is 18, radius is 9.
Area = pi (3.14) x r*2 (9*2 = 81) .. 3.14 x 81 = 254.34 sq cen = total area of circle.
A circle is 360 degrees, the shaded area is 270 degrees. the shaded area is 3/4 (270/360) of the area of the circle.
254.34 x 3/4 = 190.755 sq cen
Hope this helps
The largest integers of the numbers is 406.
<h3>How to find the five consecutive positive integers?</h3>
The sum of five consecutive positive integers is 2020.
Therefore,
let
the first positive integer = x
Hence,
x + x + 1 + x + 2 + x + 3 + x + 4 = 2020
5x + 10 = 2020
5x = 2020 - 10
5x = 2010
x = 2010 / 5
x = 402
largest integer = 402 + 4 = 406
Therefore, the largest integers of the numbers is 406.

The expression 2×2×2×5 shows the prime factorization of 40.
Prime factorization:
The number 40 is equal to
2 x 2 x 2 x 5, or = 40
23 x 5. = 40
<h3>
What does prime factorization serve as?</h3>
In mental arithmetic, fractions, finding square roots, and computing the HCF and LCM of two smaller numbers, prime factorization is a highly helpful tool when working with whole numbers. A whole number higher than 1 whose only elements are 1 and itself is referred to as a prime number. A whole number that may be split evenly into another number is referred to as a factor.
