Answer:
≈ 26.39 inches
Step-by-step explanation:
The circumference of a circle is 2πr or πd with r meaning radius and d for diameter. Since we know the diameter already, we can substitute the value in for d:
C = π(8.4) = 8.4π ≈ 26.39
Answer:
Step-by-step explanation:
Answer:
y=-1/3x
Step-by-step explanation:
We use the linear equation of y=mx+c
Y=c
We know that y=0 and that m=-1/3, therefore we plug it in the formula.
y=-1/3x+0
y=-1/3x
The figure shows a right triangle at each corner with legs 3 and b and hypotenuse 4. The Pythagorean theorem tells you the sum of the squares of the legs is equal to the square of the hypotenuse:
3² + b² = 4² . . . . . . put the numbers into the Pythagorean formula
9 + b² = 16 . . . . . . . evaluate the squares
b² = 16 - 9 = 7 . . . . subtract 9 to isolate the variable
b = √7 . . . . . . . . . . undo the square operation by taking the square root
