3/20 is the same as 15/100 or 15%
so 10×3/20 would be the same as 10×15% or 150%
Is that what you were asking?
Step-by-step explanation:
Circumference of wheel = πd = 0.75πm.
How far the car travels per minute
= 60s * (14m/s) = 840m.
Hence number of revolutions per minute
= 840m / 0.75πm
= 356.507....
= 357. (nearest whole number)
Answer:
2x2x47=188
Step-by-step explanation:
<span>smallest side = x
</span><span>hypotenuse = 4x
</span><span>By the Pythagorean theorem:
</span><span>
(4x)</span>² - x² = (√735)²
16x² - x² = 735
15x² = 735
x² = 735/15
x² = 49
x = √49
x = 7 ← smallest side
hypotenuse = 4x = 4*7 = 28
Answer:
Area = 4π
Step-by-step explanation:
4π
divide the 4 by 2 because circumference=2π
the area of a circle is πr²
multiply the 2 with itself π2²
area = 4π
i believe.
