Surface Area= 2.pi.r.h+2.pi.r^2
Surface Area =2.pi.3/2.10+2.pi. (3/2)^2
Surface Area =30pi+4,5.pi
Surface Area =34,5.pi
Answer:
45
Step-by-step explanation:
Since the values are relatively small substitute i = 1 to 5 into 3i and sum
(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)
= 3 + 6 + 9 + 12 + 15
= 45

Answer:
1296 m³
Step-by-step explanation:
Volume = area * height.
Take any of the given faces. I have taken 12m & 12 m.
Area of this face = 1/2 * 12m * 12m
= 72 m²
Height = 18 m.
Thus,
Volume = 72m² * 18m = 1296 m³
