Answer:
Surface area of Cube Y is 3 times greater than the surface area of cube X
Step-by-step explanation:
Surface area of a cube,A = 6s²
Where,
s = side length
Cube X has a side length of 1,
Surface area of cube, X = 6s²
= 6 * 1²
= 6 * 1
= 6
cube Y has a side length of 2
Surface area of cube, Y = 6s²
= 6 * 2²
= 6 * 4
= 24
How much greater is the surface area of cube Y than cube X?
Surface area of Cube Y is 3 times greater than the surface area of cube X
Answer:
A
Step-by-step explanation:
One complete turn is 1 perimeter (aka circumference).
We have to find the length it turned, hence, its circumference.
The formula for circumference (C) of a circle is:
Where r is the radius
The radius is HALF of diameter. Given diameter is 250, the radius is:
r = 250/2 = 125 feet
Now, substituting in formula we have:
So, it turned 785.4 feet with 1 rotation.
The correct answer is A
9514 1404 393
Answer:
123.6 m²
Step-by-step explanation:
The area is given by the formula ...
A = (AB)(AD)sin(∠A)
A = (7 m)(20 m)sin(62°) ≈ 123.6 m²
Answer:
15.7
Step-by-step explanation:
'6' is in the tenths place in 15.6895. The digit following this '6' is '8,' which requires rounding up this '6' to '7.'
Thus, to the nearest tenth, we get 15.7.
