Answer:
90π units²
Step-by-step explanation:
(refer to attached)
Total Surface are off a right cylinder = area of its ends + area of curved surface
Given radius, r = 3 units and height, h = 12 units
Area of 2 ends,
= Area of 2 circles
= 2 x πr²
= 2π (3²)
= 2π (9)
=18π units²
Area of curved surface,
= 2πrh
= 2π(3)(12)
= 72π units²
Hence,
Surface area = 18π + 72π = 90π units²
X+3y=14
-x. -x
3y=-x+14
Divide them all by 3
Y=-x/3+14/3
Y-intercept= 1/3
Answer:
- 1.33 per pound
- 6.65 for 5 pounds
Step-by-step explanation:
To find cost per pound, divide cost by pounds.
3.99/(3 lb) = 1.33/lb . . . . cost per pound
The cost of 5 pounds will be found by multiplying that by 5:
(1.33/lb)(5 lb) = 6.65 . . . cost of 5 pounds
Answer:
B
Step-by-step explanation:
Answer:
1/ 5²
Step-by-step explanation:
= 5³ × 1/5⁵
= 125 × 1/5⁵
= 125/3125
= 1/25 or 1 / 5²
