Answer:
![49\pi \approx 153.94\text{ m}^2](https://tex.z-dn.net/?f=49%5Cpi%20%5Capprox%20153.94%5Ctext%7B%20m%7D%5E2)
Step-by-step explanation:
The area of a circle is pi multiplied by the radius squared:
.
The figure shows a diamater equal to 14 m, so the radius is half of that, 7 m.
![A=\pi(7)^2=49\pi](https://tex.z-dn.net/?f=A%3D%5Cpi%287%29%5E2%3D49%5Cpi)
A calculator gives a decimal approximation of 153.94 meters squared. (![\pi\approx3.1415927](https://tex.z-dn.net/?f=%5Cpi%5Capprox3.1415927)
The distance between two points is calculated through the equation,
d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values from the given above,
d = √(4 - -4)² + (4 - -4)²
d = 8√2 = 11.31
The distance between the points is approximately equal to 11.31. The value that Jason presented is not the real distance because it does not account for the other set of coordinates.
180 degrees in a triangle therefore you will subtract 54 and 79 from 180 which then gives you the answer --47--
do you understand how to do it now ?
T=90 because:
first, solve for other variables
(131)2+y*2=360 vertical angles are equal
y= 49, then solve for x,
x=180-73-42
x= 65
another side is 66 in x triangle.
then find the vertical angle between the z and the t triangle,
73+66+t triangle side= 180
t triangle side =41
49+41+t=180
t=90
