Answer:
13.) 314.2 in²
15.) 181.5 ft²
Step-by-step explanation:
The area of a circle is found using the equation:
A = πr²
In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).
For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".
A = πr²
A = π(10)²
A = π x (100)
A = 314.2 in²
For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.
diameter = 15.2 ft
radius = 7.6 ft
A = πr²
A = π(7.6)²
A = π x (57.76)
A = 181.5 ft²
1 5/6 × 2= 2.66 or 2 2/3.

Answer:
.52 x 10^7
Step-by-step explanation:
1 x^3 = b^9 / 125
x = b^3 / 5
2. x^2 = 1 /2.16
x = sqrt 1/2.16
x = +/- 0.68 to nearest hundredth
Hello!
Assuming that AC contains the points we are given, we will look at both values. We can see that both x values are the same, -2, so this is a vertical line segment. Therefore we need to find the difference between our y-values.
1--3
1+3
4
Therefore, the distance is 4 units.
I hope this helps!
