Answer:
3446.464 m³
Step-by-step explanation:
280 cm=2.8 m
S=πr²×h×14
=3.14×2.8²×10×14
=3446.464 m³
Answer:
see graph of y=3/4 x-4
Step-by-step explanation:
Assuming you mean

Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.
You have to be careful on how you write these equations down. It might very well be that you meant:
or 
However, those are more complex so I'm hoping for the first one... ;-)
Inverse property of multiplication
(a*1/a=1)
Answer:
4
Step-by-step explanation:
BCD is a right triangle. The Pythagorean Theorem applies; a^2 + b^2 = c^2, with c being the hypotenuse. a^2 + 9 = 25, so a^2 = 16, so a = 4
