Answer:
Step-by-step explanation:
Surface area = 4*lateral faces + 2*bases
- A = 4*30 + 2*25 = 170 ft²
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
- -- There are 260.714 weeks total in 5 years.
But you can round by doing this:
52*5=260
This is because you have 52 weeks in a year and 55 years so you multiply.
