V = (1/3) π r² t
= (1/3) π (10 cm)². 16 cm
= (1/3) π (100 cm²). 16 cm
= (1/3) π (1600 cm³)
= (1600π)÷3 cm³ (B)
8 x 1 = 8
8 x 1/2 = 4
8+4 =12
therefore, 8 x 1 1/2 = 12
62,000 is reasonable (because of rounding)90*690=62,000
Charges 0.50 per mile with a 5 dollar surcharge. Spending at most 30 dollars, the equation would be:
0.5x+5
30
To find how many miles they can travel/the solution, solve the inequality:

Subtract 5 from both sides.

Divide both sides by 0.5.

They can travel (at most) 50 miles.
Hope this helps :)
Its 324 due to the fact that 18 would come out to be 9 so twice of 9 is 18 and 18 times by 18 equals 324
