Area of shaded region = Area of larger circle - Area of smaller circle.
We know, Area of a Circle = πr²
So, A = πr₁² - πr₂²
A = π (r₁² - r₂²)
A = π(10.2² - 5.4²)
A = 3.14 (104.04 - 29.16)
A = 3.14 (74.88)
A = 235.12
In short, Your Answer would be 235.12 cm²
Hope this helps!
Answer:
$22.40
Step-by-step explanation:
For this question you have to use decimal multipliers to work out the sale price of the cola given the information that in a grocery store, a $32 case of soda is labelled get a 30 % discount so to use decimal multipliers we have minus 100 by 30 and then divide by 100
→ We have to minus 100 by 30
⇒ 70
→ And then divide by 100
⇒ 70 ÷ 100 = 0.7
0.7 is the decimal multiplier for this question so we multiply it by the case of soda price with is $32 so
32 × 0.7 = 22.4
The sale price of the case of soda is $22.40 considering a 30% discount on a $32 case of soda
