The area of the circle is 16*16*pi=256pi. We can calculate 3/4 of the circle's area for the part not represented by the triangle and the shaded area, and then add in the triangle. 3/4 of the circle's area is 192pi.
The triangle is a right triangle with two legs of length 16. Therefore, it's area is 16*16/2=128, and the total area is 192pi+128, or 731.2.

Given expression,
Since, for the 7th partial sum of this summation.
we take i from 1 to 7.
Thus, the required sum is,
Answer:
160
Step-by-step explanation:
Consecutive numbers have a difference of 1 between them.
Let n be the first number then n + 1 and n + 2 are the second and third numbers. Summing them gives
n + n + 1 + n + 2 = 477, that is
3n + 3 = 477 ( subtract 3 from both sides )
3n = 474 ( divide both sides by 3 )
n = 158
The 3 consecutive numbers are 158, 159, 160
The third number is 160
Given:
Number of trips = 7
Distance from the school to the museum = 36 miles.
To find:
Write and solve equations to find how many miles the bus driver drove for the 7 trips.
Solution:
Let x be the number of trips and y be the total number of miles the bus driver drove.
Distance from the school to the museum = 36 miles.
1 trip means from the school to the museum and then from the museum to the school.
Distance covered in 1 trip = 2×36 = 72 miles.
Distance covered in x trips = 72x miles.
Substitute x=7 in the above equation to find the total distance the bus driver drove for the 7 trips.
Therefore, the bus driver drove 504 miles for the 7 trips.
