Step-by-step explanation:
Radius is same in both cones....
Slant height of lower cone = 50 cm ( by applying Pythagorean theorem )
TSA of the lower cone = 22/7 × 14 × ( 14 + 50 )
= 2816 cm^2
Total height of the solid = 52.8 cm
Height of the upper cone = 52.8 - 48 = 4.8 cm
TSA of the upper cone = 22/7 × 14 × ( 14 + 4.8 )
= 827..2 cm^2
TSA of the solid = 2816 + 827.2 = 3643.2 cm^2
126, I took the practice already.
All I did was add all A's, B's, and C's separately. Than I added them all together and got 316 total surface area. I tried but I learned this sooo long ago so i'm sorry if you get it wrong. Good Luck!
Minutes. Because you cannot concert minutes to hours.
1 hour= 60 Minutes
2 hours= 120 Minutes
I think it would be (2,-2)
Because translating it 3 units down would be like (x,y)—> (x+0,y-3) giving you (-2,-2) then over the Y axis would be (-x,y) giving you (2,-2)
