Answer:
Step-by-step explanation:
if we need to approximate,
the radius=125, the diameter is d=250
we estimate that pi=3
C=3*250=aprox 750
the closest number is 785
Answer:
20 cm^2
Step-by-step explanation:
Sectioned it off and multiplied the length by the width
11. you do 3x3=9 then plus 9+2 = 12 then 12 x 12 = 144
sorry idk 10.
Answer:
A
Step-by-step explanation:
All triangles have 180 degrees, these set of measures do not add up to 180°. They add up to 181°, so it is the answer.
7x+1 = (1/3)
2x + 2y = 28
Systems of equations.
Solve equation with single variable first.
7x+1 = (1/3) , x = (-2/21)
Substitute the value of x in second equation and solve for y.
2(-2/21) + 2y = 28, y = (296/21)
I’m assuming that isn’t the correct answer because you wrote the first equation incorrectly.
