Answer:
3077.2
Step-by-step explanation:
A circle's mass is found by
Pie times R^2
7^2 is 49, times 3.14 is 153.86
then you Multiply 153.86 by 20 which gives you 3077.2
Hello from MrBillDoesMath!
Answer: 215
Discussion:
Let's start by rewriting the monomial as
215 x^18 y ^3 z^21
Now..
x^ 18 = (x^6)^3
y^3 = (y )^3
z^21 = (z^7)^3
So those terms are already cubes! The only remaining candidate is the number 215, which is not a cube.
Thank you,
MrB
Answer:
<u>d = 2r or d = C/π</u>
Diameter is equal to two times the radius or Circumference/π
<u>C = 2πr</u>
Circumference is equal to two times π multiplied the radius
<u>A = π * r²</u>
The area of the circle equals to π multiplied by the radius squared
Step-by-step explanation:
Let's find the formulas for d, C and A
d = diameter
C = Circumference
A = Area
r = radius
π ≅ 3.1416
d = 2r or d = C/π
Diameter is equal to two times the radius or Circumference/π
C = 2πr
Circumference is equal to two times π multiplied the radius
A = π * r²
The area of the circle equals to π multiplied by the radius squared
Answer:
x = 21 / 228
Step-by-step explanation:
4x - 10y = - 3 -----> equation 1
112x + 5y = 12 -----> equation 2
Multiply 2 on both sides in the equation 2,
2 ( 112x + 5y = 12 )
224x + 10y = 24 -----> equation 3
Add equations 1 & 3,
4x - 10y = - 3
224x + 10y = 24
_____________
228x + 0 = 21
228x = 21
x = 21 / 228
Answer:
10x^2+3y
Step-by-step explanation:
Add together the x^2 and the y's, so your equation is (x^2+9x^2)+(7y-4y)=10x^2+3y.
(hope this helps :P)
