Answer:
≈ 660.5 in²
Step-by-step explanation:
The surface area (A) of a sphere is calculated using the formula
A = 4πr² ← r is the radius
Given diameter = 14. 5 then radius = 7.25, thus
A = 4π × 7.25² = 4π × 52.5625 ≈ 660.5 in²
So if Hugo has saved $10 the first week and $6 for the next 6 weeks the answer would be $46.
you can either add up 6 six times or you can multiple 6 by 6.
6+6+6+6+6+6=36 or 6×6=$36
then you add the $10 from the first week & the $36 from the $6 you saved for 6 weeks to get your final answer of $46.
$36+$10=$46
Answer:
D. No, the 
should have canceled out in step 4 making the correct answer 5.5mm.
Step-by-step explanation:
All the steps that Arden took were correct up until the last step:
1. V = Bh ⇒ 88 = *4^2 * h = 16
2. Divide by 16 from both sides: h = 88 / 16 = 88/16 = 5.5
Arden forgot to cancel out the pi from both the numerator and denominator, so her answer should have been 5.5 mm, not 5.5 mm.
Thus, the answer is D.
Hope this helps!
