Answer:
The formula to determine the circumference is: 2 x 3.14 x radius. All you need to do is plug in the value of the radius, 56, and multiply it by 2 and 3.14.
Step-by-step explanation:
It should be 715, i don’t understand why that isn’t one of the choices.
you’re supposed to multiply everything
Its impossible to draw a trapezoid with just three right angles.
a trapezoid has 4 sides, which means all the angles inside the trapezoid must add up to 360 degrees.
if you have just 3 right angles (90x3), you already use up 270 degrees. Leaving you with just 90 degrees left, which is also a right angle. That means, there has to be four, if you have at least 3.
Surface area of a cuboid
= [2(length)(width)] + [2(width)(height)] + [2(height)(length)]
= {[2(4)(2.5)] + [2(2.5)(2)] + [2(2)(4)]} units²
= (20 + 10 + 16) units²
= 46 units²
