25 because $518 ( their total ) divided by $21 ( the amount for EACH uniform) is 24.6 which isn’t possible so round it to 25
Area=pi times radius^2
area=36pi
36pi=pi times radius^2
divide both sides by pi
36=radius^2
square root both sides
6=radius
2radius=diameter
2 times 6=12
radius=6
diamater=12
the answers area A and D
(if you know your radius and diameter, you would know that diameter is 2 times radius and you could eliminate 2 choices imedietly (B and C))
Given
Endpoints of the diameter (5,2) and (-7,4)
Step One
Find the center
Center = (x2 + x1)/2 , (y2 + y1)/2
x2 = -7; x1 = 5; y2 = 4; y1 = 2
Center = (-7 + 5)/2 ; (4 + 2)/2;
Center = (-1 , 3)
Step Two
Find the radius squared using the distance formula. Use (5,2) as the second point. The other point is the center.
Distance squared = (5 - - 1)^2 + (2 - 3)^2
Distance squared = ( 6)^2 + (-1 )^2
Distance squared = 37
Step Three
State the circle's formula
(x - - 1 )^2 + (y - 3)^2 = 37
(x + 1)^2 + (y - 3)^2 = 37
Convert 2/5, 1/4 and 7/10 to fractions with like denominators.
Since 8/20,5/20 and 14/20 have the same denominator, add their numerators to add them up.
Answer:
If a solar Panel is 3 feet long and 2 feet wide then the area is 6 feet squared
then 1700/ 6 which is 283 1/3 so just round it down to 283
