Step-by-step explanation:
You use the formula πr^2 for the area, where r is the radius of the circle which is equal to half the diameter
Answer:
Its perpendicular
Step-by-step explanation:
You can solve the equation to get x=-2.5 and y = -7.5 so they intersect there, but they intersect at 90 degrees so its perpendicular.
-7 degrees fahrenheit is warmer
Answer:
12/5 or 2.4 cm³
Step-by-step explanation:
3*4/3*3/5=12/5 or 2.4 cm³
In order to solve, set up a proportion: 22/126=x/100. Cross multiply: 2200=126x. Divide by 126 on both sides: 17.46%=x
