Answer:
602.9 cm²
Step-by-step explanation:
==>Given:
A hemisphere with radius of 8cm
π = 3.14
==>Required:
Total surface area of hemisphere
==>Solution:
The total surface area of the hemisphere (TSA) = Curved surface area of hemisphere (CSA)+ base area (BA)
If surface area of a sphere is given as 4πr², therefore, the area of a hemisphere would be ½ of 4πr² = 2πr²
CSA = 2πr²
Base area (BA) = area of circle = πr²
Thus, TSA = 2πr2 + πr2 = 3πr2
TSA of hemisphere = 3 × 3.14 × 8²
TSA = 3 × 3.14 × 64
TSA = 602.88
TSA of hemisphere = 602.9 cm² (approximated to 1 decimal place)
Yes; LNM ~ OQP because of the SAS~ postulate

hope this helps
can i plz get brainliest </span>
Answer:
X = 8 because the two given angles are alternate interior, meaning they are equal. Knowing that, you set up the equation 6x-2=46 and solve algebraically for 8.
