- Diameter = 51 cm
- Radius (r) = 51 cm ÷ 2 = 25.5 cm
- π = 3.14
- Circumference
- = 2πr
- = 2 × 3.14 × 25.5 cm
- = 160.14 cm
- Area of a circle
- = πr^2
- = 3.14 × (25.5)^2 cm^2
- = 3.14 × 25.5 × 25.5 cm^2
- = 2041.785 cm^2
Hope you could understand.
If you have any query, feel free to ask.
-2(-2)+3=7
-2(0)+3=3
-2(4)+3=-5
the answer would be 161.6 mph
R = rate
A = P(1-r)^t
A^t = P(1-r)
A^t/P = 1-r
(A^t/P)-1 = -r
r = -((A^t/P)-1)
For the first die, 5 out of 6 are not 1.
That is 5/6.
For the second die, 3 out of 4 are not 1.
That is 3/4.
Multiply 5/6 by 3/4 to get the probability.
5/6 x 3/4 = 20/72
Simplify once to get 10/36.
Do it again to get 5/18.
In decimal form it is 0.2777 and in percent form it is 27.77%.
Hope this helps!
