Surface area of a sphere=4pi(r^2)
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
Answer:
Variables:
→ The number of hours the worker worked
→ The number of shirts the worker made.
System fo equations:
Step-by-step explanation:
Let be
the number of hours the worker worked and
the number of shirts the worker made.
Since:
- Jason must pay the worker $25 per hour (which can be represented with
). - He must pay $1.75 per shirt for material costs (which can be represented with
). - The total expenses were $270.
You can write the following equation:

Knowing that the worker created an average of 5 shirts per hour, you can write the other equation:

Therefore, with this equations you can set up the following system of equations, which could be used to determine the number of hours the worker worked and the number of shirts the worker made:
Answer:
-19
Step-by-step explanation:
if you know subtraction you will know this just subtract 15 from 34 easy can you mark me brainly est. thx
Answer:
21
Step-by-step explanation:
14+7=21.
You do this to allow you to get that outcome, because you know 7*7=49.
Therefore 21-14=7
7*-7=49
