Answer:
Step-by-step explanation:
Circumference is 40 in and area is 150 in²
Step-by-step explanation:
- Step 1: Find the circumference of the circle when radius = 7 in
Circumference = 2πr = 2 × 22/7 × 7 = 44 in ≈ 40 in
- Step 2: Find the area of the circle.
Area = πr² = 22/7 × 7² = 154 in² ≈ 150 in²
So what you should do is
15% off, then add tax or
2075 times 0.85 times 1.185=2090.04 about
you can't just add and subtract percents because they are percents of different things
what he did was
he found 15% of 2075 and 18.5% of 2075 then found the difference and added to 2075 to find his total
what he should have done is
found the discounted price (15% off) then found the tax on that
first way
2075 times 0.15=311.25
2075-311.25=1763.75
1763.75 times 0.185=326.29375
1763.75-326.29375=2090.04
2nd way (easy, if you understand commutative property and stuff)
100-15=85
1+0.185=1.185
2075*0.85*1.185=2090.04
answer should be $2090.04
I believe the term is a "radical"
Hope this helps!
