Answer: The area is approximately 314 ft^2
Step-by-step explanation:
Well if the diameter is 20 feet then the radius will be 10 because the radius is half the diameter, and to find the area of a circle, you use the formula
A= 
where A is the area and pi times the radius squared.
We will represent pi by 3.14
A= 3.14* 10^2
A= 3.14 * 100
A = 314
Make this on form of a simultaneous equation:
assume jelly beans is J and trail mix is T
8J+4T=21
3J+2T=9
then solve
multiply the first equation by 3 and second equation by 8(SO THE J CAN DISAPPEAR[ELIMINATION METHOD])
24J+12T=63
24J+16T=72
Subtract
-4T=-9
T=0.44
then substitute the T to any one of the equation
3J+2(0.44)=9
3J+0.88=9
3J=8.12
J=2.71
therefore, jelly beans= $2.71 and trail mix=$0.44
Step-by-step explanation:
-13=4v+8-7v
-13-8=-3v
3v=21
v=7
Answer:
radius= 14
Step-by-step explanation:
the distance around the edge is given by = 2πr
88= 2 (22/7)*r⇒ r= 88*7/44= 14
For a triangle, the measure of the exterior angle is the sum of the angles that are non-adjacent to the exterior angle. If the given angles, L and J, are non-adjacent angles to the exterior angle at K, then the measure of the exterior angle is
45 + 65 = 110 degrees
