The perimeter of an ellipse is given by:
P = (2 * pi) * root ((a ^ 2 + b ^ 2) / 2)
Where,
a: semi-major axis
b: Semi-minor axis
Substituting the values we have:
P = (2 * 3.14) * root (((30/2) ^ 2 + (12/2) ^ 2) / 2)
P = 71.74058266
Round off to the nearest whole number
P = 72 mm
Answer:
B.72 mm
Answer:
How do you find volume when given surface area?
Since the base area is given, simply multiply the area of the base times the height to calculate the volume. *Reminder: Volume is measured in cubic units. The volume of the square prism is 225 cubic feet.

a=4
Answer:
D
Step-by-step explanation:
Answer:
Multiproperty
Step-by-step explanation:
To solve this problem, we use different properties to arrive at our answer.
Given expression;
4(x + 3) = 20;
First we use the distributive property to expand;
4x + 12 = 20
Now use subtraction property by adding (-12) to both sides;
4x + 12 + (-12) = 20 + (-12)
4x = 8
you can now divide by 4,
x = 2
