Answer:
28.26
Step-by-step explanation:
A = r^2
So the equation is. Area of circle = pi(3.14) * radius(3) to the power of 2 (^2)
A = 3.14(3)^2
A = 3.14(9)
A = 28.26
Answer:
Try this solution, it consists of two parts (MN=8).
Step-by-step explanation:
Answer:(0,0) (-1,0) (-1,3)
Step-by-step explanation:
scf 0.5 is shrinking the shape by a 1/2
The coordinates of a point of enlargment is (3,1)
so you work out the vectors of each corner than times it by 0.5
The vector of one cooridnate is (-6 -2)
-6x0.5=-3
-2x0.5=-1
so the vector is -3 -1 from the point of enlargment is the shape .
(-8 -2 ) is the coodinates of the next vector so
(-4 -1)
Then the last
(-8, 4)
(-4,2) vector for the last coodinate
sorry i couldn't write out the vector properly in the right notation .

Step-by-step explanation:
15 less than 3 times n is 3n - 15, thus
n + 3n - 15 = 101 ← equation modelling the situation
4n - 15 = 101 ( add 15 to both sides )
4n = 116 ( divide both sides by 4 )
n = 29
