A+b+c = 131
b = 7 + 2a and c = a - 12
so a + 7+2a + a-12 = 131
then 4a -5 = 131
then 4a = 136
and a = 34....so b= 75 and c = 22....check 34+75+22=131√
Answer:
Step-by-step explanation:
The equation for a cylinder is the radius of the circle times pi squared, multiplied by the height. 3 squared is 9, times pi is 9(pi). If we multiply this by the height, the answer is 90(pi) centimeters in volume.
12 cm³ or 12 mL
Step-by-step explanation:
To find the volume of object A, we’ll use the formulae; L * W * H;
Where L = Length
W = Width
H = Height
Since all values are given, well just multiply them;
4 * 3 * 1 = 12 cm³
1 cubic centimeter is equivalent to 1 mL so we can also write the answer as 12 mL
