Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) = 4×pi×r²
our radius r (half the diameter) here is 5m.
=>
As = 4×pi×5² = 4×3.14×25 = 100×3.14 = 314 m²
Answer:
96 pizzas
Step-by-step explanation:
First, we have to determine how many pizza he can make in one minute = 8/15 = 0.533
Convert 3 hours to minutes = 3 x 60 = 180 minutes
The number of pizzas he would make in 3 hours = 180 x 0.533 = 96 pizzas
bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient

<h3>Given:</h3>
<h3>Note that:</h3>
- l= length
- b= breadth
- h= height
<h3>To find:</h3>
The volume of the given rectangular pyramid.
<h3>Solution:</h3>

First, multiply the length (5), breadth (4) and height (3).


Now, divide 60 by 3.


<u>Therefore, the volume of the given rectangular pyramid is 20 cubic meters.</u>
