Answer:
D
Step-by-step explanation:
The formula for the circumference of a circle is 2r. So if we know that C=60then we can trace our steps back. We are given that pi remains constant so we are left with the 2r from the formula and a 60. 60/2 =30.
The radius is 30cm
Answer:
101 m^3
Step-by-step explanation:
v = π * r^2 * h/3
= π * 4^2 * 6/3
v= 100.53 m^3
v= 101 m^3 to the nearest cubic meter
Answer:
2 ( e^3 + 1 )
Step-by-step explanation:
The path of the attached Rectangle is anti-clockwise
and the Integrand: P( x, y ) dx + q ( x , y ) dy
P( x, y ) = ye^x
q ( x , y ) = 2ex
hence : dq/dx - dp/dy = 2e^x - e^x = e^x
attached below is the remaining solution
using Green's theorem
-5.25 -(-7.5) (Conversion to decimals cuz' it's easier for me to type)
-5.25 + 7.5 (Subtracting a negative is like Adding a Positive)
7.5 - 5.25 (Rearranging)
2.25 (Subtracting)
2 1/4 Final Answer.
To do it w/o converting to decimals, make sure the fractions have the same denominator.
1/3 opposite is -1/3 less than 12
