513/2=256.5
which means 256 and 257 are the answers
We are given
area of sphere is 200.96cm^2
it means that we are given surface area
so, we can use surface area formula
where S is surface area
r is radius
so, firstly we need to find radius or r
we can solve for r
now, we can find volume
we can plug r
now, we can find volume
.............Answer
12.25 is the scale factor if the pre image is 12 and the image is 147
For this case we must solve a system of two equations with two unknowns, given by "x" and "y".
We have:
We multiply (2) by -1:
We add (1) and (3):
Clearing x:
We substitute in (2)
Thus, the solution of the system is
Answer:
The solution of the system is
Answer:
90 in²
Step-by-step explanation:
First,check the figure I provided .
Area of the figure = area1 + area2 + area3 + area4
= (3×2) + (7×7) + (7×2) + (7×6)÷2
= 6 + 49 + 14 + 21
= 90
