Answer:
3120
Step-by-step explanation:
Multiply 52 by 60 and it equals 3120
8 9/ 25 = 8 36/100
8 36/100 = 8.36 = 836%
836 is the answer
Answer:
1.a=5cm
Surface area :6a²=6×5²=150cm²
2.r=3cm
h=5cm
total surface area of cylinder =2πr(r+h)
=2π×3(3+5)=48π cm²
3.
l=4m
b=5m
h=2m
now.surface area =2(lb+lh+bh)
=2(4*5+4*2+5*2)
=76m²
4.
r=6cm
surface area =4πr²=4*π*6²=144πcm²
5.
slant height (S)=8cm
length =breadth=(L)=4cm
Surface area of pyramid =area of base + 2* area of trainglular face
=L²+2*S*L
=4²+2*8*4
=80cm²
36 min painted 420ft²
1 min——> 420/36
=11 2/3 ft²
∴ 30 mins ——-> 11 2/3 x 30
=350 ft²
