Answer:
Dori has $48 left.
Step-by-step explanation:
The boat costs twice as much as the goggles, divide 8 by 2 to find the price of the goggles. The price of the goggles is $4.
Add $8 and $4 to get $12. This is the total money Dori spent.
Since this is 1/5 of her money, multiply $12 by 5 to get $60. This is the money Dori had.
Subtract the $12 from the $60 to get $48. This is the money Dori has left.
Answer:
1254.24
Step-by-step explanation:
Total area = sum of area of half circles and square
Area of square = 576
Area of half circles = 216π
So total area 576 + 216π
It says use 3.14 for π
So we get total area = 576 + 216(3.14)
==> multiply 216 and 3.14
total area = 576 + 678.24
==> add 576 and 678.24
total area = 1254.24
