Area of a circle = πr²
Replacing with radius = 8.4 in:
Area of a circle = π(8.4)²
Area of a circle = 221.6708 in²
This area corresponds to 2π radians. To find the area corresponding to 2.37 radians, we can use the next proportion:
Solving for x:
Answer:
I think it is the second one not sure
Step-by-step explanation:
Substitute W = 9, L = 4 into P = 2L + 2W
P = 2(4) + 2(9)
P = 8 + 18
P = 26
Answer
P = 26
here ratio is 1:8
total parts 1+8=9
so first we divide 270 by 9 which is 30
first part is 1*30 which is 30
second part is 8*30 which is 240
therefore £270 in the ratio 1/8 is 30/240
