Answer: Diameter is increasing as centimeter per hour.
Step-by-step explanation:
Alright, lets get started.
The formula for volume of sphere is given as V :
The volume of a sphere is increasing at a rate of cubic centimeters per hour.
It means :
Taking derivative with respect to t
at the instant the radius of the sphere is 3 centimeters, means
As
Hence diameter is increasing as centimeter per hour. : Answer
Hope it will help :)
Given:
5 shirts ; 25 given to parents for the supplies ; 60 remaining money.
x = total cost of supplies for making the shirt
60 = 5x - 25
60 + 25 = 5x
85 = 5x
85/5 = x
17 = x
<span>The equation 5x−25=60 can be used to solve this problem.

Answer: there are 580 seats
Step-by-step explanation:
The number of seats in each row is increasing in arithmetic progression.
The formula for determining the sum of n terms of an arithmetic sequence is expressed as
Sn = n/2[(2a + (n - 1)d]
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 10 seats
d = 2 seats (the seats in each row are increasing by 2)
n = 20(number of rows)
We want to determine the number of seats in 20 rows. Therefore
S20 = 20/2[(2×10 + (20 - 1)2]
S20 = 10(20 + 38) = 10×58
S = 580
Hello!
To find the area of a circle you do
the "r" stands for radius which is half the diameter
So we do
Which gives us the answer of 314.16
Hope this helps!
