Brayden stated that a flying disc had a circumference of 43.96 in. Eliza wanted to find the area of the same flying disc. What is the area of the flying disc rounded to the nearest whole number? Both Brayden and Eliza used 3.14 for π.
2 pi r = 43.96
so r = 21.98 /pi
A = pi r^2 = pi (21.98/pi)^2 = 483.12 / 3.14 = 153.86
about 184 I think
Ah, Brayden and Eliza, a dynamic duo in their quest for mathematical glory! Now, to find the area of the flying disc, we need to use the formula A = πr², where A represents the area and r represents the radius.
First things first, let's find the radius (r). Since Brayden provided us with the circumference (43.96 in), we can use the formula C = 2πr to solve for r.
43.96 = 2πr
Now, let's isolate r:
r = 43.96 / (2 * 3.14)
Calculating that out, we get:
r ≈ 7
Now that we know the radius (r ≈ 7), we can plug it into the formula to find the area (A):
A = π * (7²)
Calculating further, we get:
A ≈ 154
So, the area of the flying disc, rounded to the nearest whole number, is approximately 154. And voila! There you have it, the answer to unravel the mystery of the flying disc's area.
To find the area of a flying disc, we need to use the formula:
Area = π * r^2
Given that the circumference of the flying disc is 43.96 in, we can use the formula for circumference to find the radius.
Circumference = 2 * π * r
43.96 = 2 * 3.14 * r
Dividing both sides by 2 * 3.14:
r = 43.96 / (2 * 3.14)
r ≈ 7 in (rounded to two decimal places)
Now that we have the radius, we can plug it into the formula for the area:
Area = 3.14 * 7^2
Area ≈ 153.86 in^2
Rounding the area to the nearest whole number, the area of the flying disc is approximately 154 in^2.
To find the area of a disc, we need to use the formula A = πr^2, where A is the area and r is the radius of the disc.
Since Brayden provided the circumference of the flying disc, we can use the formula for circumference C = 2πr to find the radius.
Given that the circumference is 43.96 in, we can solve the equation for r:
43.96 = 2 * 3.14 * r
Dividing both sides of the equation by 2 * 3.14, we get:
r = 43.96 / (2 * 3.14) ≈ 7
Now that we have the radius, we can calculate the area using the formula:
A = 3.14 * (7^2)
Simplifying the equation, we get:
A = 3.14 * 49
A ≈ 153.86
Rounded to the nearest whole number, the area of the flying disc is 154.
