The first quartile of the data set is 28 because it is the median of the lower set.
The given terms can be divided into two sections. First section is for the numbers and the second one for the letters.
1st section: 1, 2, 3, and 4
2nd section: I, L, F
I is the 9th letter in the alphabet, L is the 12th letter, and F is the 6th letter in the alphabet.
The pattern observed:
I to L: 12 - 9 = 3
L to F: 6 - 12 = -6
Next letter should be +9. This means that the letter should be 9 places higher than F. The letter should be O which is the 15th letter.
The radius of a cone with a curved surface area of 140π cm² and a slant height of 5 cm will be 28 cm.
<h3>What is curved surface area?</h3>
The region with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Total Surface Area is the combined area of the bases and the curved surface. The measurement of a solid's curved surface area is its outer area, which excludes the top and bottom extensions. Surface area of the cylinder that is curved: A right circular cylinder is the solid that results when a rectangle circles around one side and makes a full revolution. The curved surface area of a cylinder (CSA) is also known as the lateral surface area and is defined as the area of the curved surface of any given cylinder having a base radius "r" and height "h".
Here,
Curved surface area of cone=πrl
=140π
l=5 cm
140π=πr*5
r=140/5
r=28 cm
The radius of cone that has 5 cm as slant height and 140π cm² as the curved surface area will be 28 cm.
