Answer:
The principal will need 26.24 m² of plastic to cover the sand pit.
Step-by-step explanation:
In order to calculate the amount of plastic, we need to find out the area of the sandpit. The shape of the sandpit is a rectangle, so we can use the formula:
A=W×H
where,
W is the width of the sandpit
L is the length of the sandpit
Therefore,
A=2.75 m × 9.54 m = 26.24 m²
The amount of plastic needed is 26.24 m²
The volume of a cylinder is given by:
V = pi * r ^ 2 * h
Where,
h: height
r: Radius
Substituting the values we have:
V = pi * (3) ^ 2 * (8)
Rewriting:
V = pi * (9) * (8)
V = 72pi cubic units
Answer:
V = 72pi cubic units
Answer:
-2
Step-by-step explanation:
Absolute value is the distance from a number to 0 on the number line, so the number can't be negative, only positive. The absolute value of -1 would be 1, therefore it couldn't be -2, or any other negative numbers.
The given expression is
TO find the equivalent expression, we use distributive property
Distributing half on 6e -3f -3/4, we will get
And that's the required equivalent expression of the given expression .
