Answer:46293
Step-by-step explanation:
Answer: Area = 490.87 meters
Step-by-step explanation:
A=πr2
r = 12.5 (1/2 of diameter)
A = 490.87 meters
Here we use the formula of area of sector, which is
Substituting 140 for theta, 11 for radius, we will get
And that's the required area wiped by the wiper blade .
Its easy here is the answer
1 + 4 = 5, in this question, there is 1 "4", and 1 + 4 = 5
2 + 5 = 12, in this question, there are 2 "5", and 2 + 5 + 5 = 12
3 + 6 = 21, in this question, there are 3 "6", and 3 + 6 + 6 + 6 = 21
So for 5 + 8, there are 5 "8", so:
5 + 8 + 8 + 8 + 8 + 8 = 45
45 is your answer
hope this helps
