Answer:
Step-by-step explanation:
r = 7 cm
h = 15cm
pi = 3.14
Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).
Area = 2* pi *r^2 = 2 * 3.14 * 7^2
Area = 2 * 3.14 * 49
Area = 307.72 Don't round this.
Cylinder body
Cylinder body = Circumference * h = 2*pi * r * h
Cylinder body = 2* 3.14 * 7 * 15
Cylinder body = <u> 659.4</u>

Total = 967.12
Rounded 967.1 Answer
Answer:
t > 8
Step-by-step explanation:
Given that :
Initial volume = 16 litres
Addition rate = 4 litres per minute
Target volume > 48 litres
Let number of minute for which water is added to achieve these = t
Mathematically,
Initial volume + (addition rate * t) > target volume
16 + 4t > 48
Collect like terms
4t > 48 - 16
4t > 32
Divide both sides by 4
4t/4 > 32/4
t > 8
Laura will need add water at 4 Litre per minute rate for more than 8 minutes

Answer:
Step-by-step explanation:
The volume of a pyramid with a square base is given by the expression suh,
where
s is the length of a side of the base.
h is the height.
From the information given,
The side length,s of the square base = 24 feet.
The height, h other pyramid = 30 feet.
Area of the square base = s^2 = 24^2 = 576
Volume = area × height × 1/3
Volume = 576 × 30 × 1/3
Volume = 5760 ft^3
