Answer:
75,076
Step-by-step explanation:
19-4 = 15
14+4 = 18
15 x 18 = 270, then add 4 which equals 274.
274 x 274 = 75,076
Answer:
18cm
Step-by-step explanation:
Area of Trapezium = 1/2(a + b) h
Where:
A = 352cm^2
h = distance between parallel sides = 16cm
a = 25cm
b = ?
352 = 1/2 (25 + b) 16
352 = (25 + b) 8
352 = 200 + 8b
352 - 200 = 8b
152 = 8b
152/8 = b
19= b
→b = 19cm
The other parallel side is 19cm.
The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.
The area can be calculated in terms of known linear measurements of the circle:
-- Area = (π) x (radius)²
-- Area = (π/4) x (diameter)²
-- Area = (1/2) x (circumference) x (radius)
-- Area = (1/4) x (circumference) x (diameter)
Any of these formulas will give you the area. The one you decide to use
just depends on what you already know about the circle.
