Answer:
27 ft^2
Step-by-step explanation:
r = 3 ft (that's the radius)
and pi = 3
A = pi r^2
or
3 * r^2
plug in r = 3
so 3 * 3^2 = 3 * 9 = 27 ft^2
(note: 3^2 = 3 * 3. Squaring means we multiply the number by itself)
You'd have to regroup twice.
Since 26 is bigger than 13, you'd need both the tens and ones places to go up by ten in order to subtract properly.
Answer:
$159.10
Step-by-step explanation:
Original price: $199
The price is reduced 10%. That means the price is now 90% of the original price.
90% of $199 = 0.9 * $199 = $179.10
The price is $179.10 after the 10% discount.
Apply the $20 coupon to reduce the price by $20.
$179.10 - $20 = $159.10
