central angle of a sector is 72° and the sector has an area of 16.2(pie) ft^2. what is the radius of the circle?
Cloud [144]
Sector area = (central angle / 360) * PI * radius^2
sector area = (72 / 360) * PI * radius^2
radius^2 = sector area / [(72 / 360) * PI]
radius^2 = 16.2 * PI / [(1 / 5) * PI]
radius^2 = 16.2 / .2
radius^2 = 81
radius = 9

the seats at a local baseball stadium are arranged so that each row has 5 more seats than the row below it. if there are 4 seats
Dvinal [7]
The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,                                          an = a1 + (n - 1) d
Solving for the 23rd term,                                            an  = 4 + (22) 5 = 114 seats
Therefore, the answer is there are 114 seats on the 23rd row.
