Answer: 423.11 m^2
Step by step explanation:
Area of a circle formula pi*r^2
First solve the area of the big circle
3.14*21^2=1384.74 m^2
Now find the are of the smaller circle
r=21-3.5=17.5
3.14*(17.5)^2=961.63 m^2
Now we can minus the small area off the big area to get the shaded area.
1384.74-961.63=423.11 m^2
So the area of the shaded region is 423.11 m^2
30, 6+9= 15+4= 19+1= 20+10= 30
Based on the cost of the calculator, the discount, the shipping fee, and the tax, the total cost of the purchase was<u> a. $80.07</u>
The cost of the calculator was:
<em>= Cost of calculator x ( 1 - discount)</em>
= 83 x ( 1 - 15%)
= $70.55
The sales tax would be:
= 70.55 x 4.5%
= $3.17
The total cost would be:
<em>= Cost + Sales tax + Shipping fee</em>
= 70.55 + 3.17 + 6.35
= $80.07
In conclusion, the total is $80.07.
