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)

Answer:
Bianca is paying $22.08
Step-by-step explanation:
If the Shirt Cost 23$ in total, and the seller took 4% off the original price, Which means
4% of 23$ = 0.92 cents, now clearly it says "IT TOOK OFF"
So, now you subtract 0.92 from the original price, to find the new price.
Here the original price is 23$,
23$ - 0.92 = 22.08$, so that means...
Bianca ended up paying $22.08
It’s a ratio and for it to equal 2 x will equal 4
11/16..." / " means divide....= 0.6875
0.688
when comparing, if it makes it easier, line ur decimals up and put a zero in any empty spaces...
0.6875
0.6880 (this is the same as 0.688)
so the one that is bigger is : 0.688 <==
