Answer:
The volume of sphere is 9200units³
Step-by-step explanation:
Given that the volume of sphere is (4/3)πr³. So use this formula to find the volume :
radius = 13units
Volume = (4/3)×π×13³
= 9200units³ (3s.f)
Answer:
f'(x) = 4
Step-by-step explanation:
- Derivative of 3 (constant number) is 0
- Derivative of 4x is 4
- f'(x) = 4 - 0 = 4
By definition, the area is given by:
A = w * l
Where,
w: width
l: length
We have two expressions for the length:
L = 14\\L = 5 + 3c
Since the length is the same, we equate both expressions:
5 + 3c = 14
From here, we clear the value of c:
3c = 14 - 5\\3c = 9
c = \frac{9}{3}\\c = 3
Then, we have that the width is given by:
W = 6c-8
Substituting the value of c we have:
W = 6 (3) -8\\W = 18-8\\W = 10
Finally, the area is given by:
A = w * l\\A = 10 * 14\\A = 140 ft ^ 2
Answer:
he should order 140 square feet
It costs $13 per book therefore you need to multiply this number by the quantity of books you are buying which is 9.
9 x 13 = 117
The cost of shipping is $5 therefore you need to add that onto the cost of the books.
$117 + $5 = $122
The cost of the order is $122.
Hope This Helps You!
Good Luck Studying :)
63/60min = 1.05k per min
(1.05k/min) * (20min) = 21k
