What is the difference in the areas of a circle with diameter 4 m and a circle with diameter 6 m?

lidiya [134]

Hello!

To solve this you need to use the equation to find the area of a circle which is

$A = \pi r^{2}$

A is area
r is radius

Solve both circles
------------------------------------------------------------------------------------------------------
Circle 1
$A = \pi 4^{2}$

Square the number

$A = 16 \pi$
------------------------------------------------------------------------------------------------------
Circle 2

A = $\pi 6^{2}$

Square the number

$A = 36 \pi$
------------------------------------------------------------------------------------------------------
Finding the answer

To get the answer you subtract the numbers

$36 \pi - 16 \pi = 20 \pi$

The difference is $20 \pi$ which is about 62.83 units

Hope this helps!

Please help me with question number 2

Mice21 [21]

Answer:

2. The area of the side walk is approximately 217 m²

3. The distance away from the sprinkler the water can spread is approximately 11 feet

4. The area of the rug is 49.6

Step-by-step explanation:

2. The dimensions of the flower bed and the sidewalks are;

The diameter of the flower bed = 20 meters

The width of the circular side walk, x = 3 meters

Therefore, the diameter of the outer edge of the side walk, D, is given as follows

D = d + 2·x (The width of the side walk is applied to both side of the circular diameter)

∴ D = 20 + 2×3 = 26

The area of the side walk = The area of the sidewalk and the side walk = The area of the flower bed

∴ The area of the side walk, A = π·D²/4 - π·d²/4

∴ A = 3.14 × 26²/4 - 3.14 × 20²/4 = 216.66

By rounding to the nearest whole number, the area of the side walk, A ≈ 217 m²

3. Given that the area formed by the circular pattern, A = 379.94 ft.², we have;

Area of a circle = π·r²

∴ Where 'r' represents how far it can spread, we have;

π·r² = 379.94

r = √(379.94 ft.²/π) ≈ 10.997211 ft.

Therefore, the distance away from the sprinkler the water can spread, r ≈ 11 feet

4. The circumference of the rug = 24.8 meters

The circumference of a circle, C = 2·π·r

Where;

r = The radius of the circle

π = 3.1

∴ For the rug of radius 'r', C = 2·π·r = 24.8

r = 24.8/(2·π) = 12.4/π = 12.4/3.1 = 4

The area = π·r²

∴ The area of the rug = 3.1 × 4² = 49.6.

3x + 2x divided by 4-2

Harlamova29_29 [7]

The answer is 5x/2 because all you have to do is add 3x + 2x too make 5x and take 4-2 which is 2 and since it can't be simplified any more, just do 5x/2. Hope this helped! :)
