Answer:
SURFACE ARE: 1068.14
Lateral surface area: 439.82
Step-by-step explanation:
A=2πrh+2πd=2×π×10×7+2×π×1000=1068.14
Al= 2drh=2×π×10×7≈439.82
100
10^2 is 100 therefore it is 100
4b2(b3+b+4)
1/8+1/2make both denominators 8
in 1/2 multiply both the numerator and the denominator by 4to get 4/8
1/8 + 4/8=5/8
