Ответ:
283 cm²
Step-by-step explanation:
r = 3 cm
2 × 3.14 × 3 (3 + 12)
= 2 × 3.14 × 3(15)
= 2 × 3.14 × 45
= 282.6 cm²
= 283 cm²
Ответ:
$60
Step-by-step explanation:
$240 = 100%
Discount = 25%
100% - 25% = 75%
75% as a decimal is 0.75
Multiply:
240(0.75) = 180
You could also do 3/4 of 240 because 0.75 is 3/4
To find out how much she saved, let's subtract the sale price from the original price:
240 - 180 = 60
Ella's mom saved $60 from the discount
