Question

BRAINLIST!!!!

You need to type a five letter word for this answer. Find the radius of each circle given the area, diameter, or circumference. Substitute your five numbers for five letters. For example, if you find the radius is 3, substitute it for the letter c (the third letter in the alphabet).

Answer 2

The correct five letter word is “HORSE”.

Given: 1. Area of Circle, A = 64π units²

           2. Diameter of the circle, d = 30 units

           3. Circumference of the circle, C = 36π units

           4. Diameter of the circle, d = 38 units

           5. Circumference of the circle, C = 31.4 units

To find: To find the radius of each circle of given area, diameter, or circumference and substitute those five numbers for five letters (i.e. if the radius is 3, then substitute it for the letter ‘C’ as ‘C’ is the third letter in the alphabet).

Solution:

We know,

Area of a circle is (πr²) units and circumference of a circle is (2πr) units, where 'r' is the radius of the circle.

Now,

1. We are given that Area of Circle, A = 64π units²

⇒ πr² = 64π

⇒ r² = 64

⇒ r = √64

⇒ r = 8

Since, r = 8

∴ The letter in the alphabet that will substitute this number is ‘H’.

2. We are given that Diameter of the circle, d = 30 units

⇒ 2r = 30     (∵ d = 2r)

⇒ r = 30/2

⇒ r = 15

Since, r = 15

∴ The letter in the alphabet that will substitute this number is ‘O’.

3. We are given that Circumference of the circle, C = 36π units

⇒ 2πr = 36π

⇒ 2r = 36

⇒ r = 36/2

⇒ r = 18

Since, r = 18

∴ The letter in the alphabet that will substitute this number is ‘R’.

4. We are given that Diameter of the circle, d = 38 units

⇒ 2r = 38     (∵ d = 2r)

⇒ r = 38/2

⇒ r = 19

Since, r = 19

∴ The letter in the alphabet that will substitute this number is ‘S’.

5. We are given that Circumference of the circle, C = 31.4 units

⇒ 2πr = 31.4

⇒ 2 × 3.14 × r = 31.4   [let π = 3.14 (approx)]

⇒ 2r = 10

⇒ r = 10/2

⇒ r = 5

Since, r = 5

∴ The letter in the alphabet that will substitute this number is ‘E’.

As the required values of the radius of the circles are 8, 15, 18, 19, and 5 respectively.

Therefore,

The substitutes of these five numbers for five letters are H, O, R, S, and E respectively.

Thus, the required five letter word is "HORSE".
