Hi there,
Sol:
Length of the swimming pool = 260 m
Breadth of the swimming pool = 140 m
Let the height of the water in the swimming pool after pouring water be h meters.
Volume of the water poured = 54600 m3
l x b x h = 54600
260 x 140 x h = 54600
h = (54600) / (260 x 140)
h = 1.5 m = 150 cm
Hope it helps
Answer:
x = 72
Step-by-step explanation:
These angles are complementary so they add up to 90:
x + 18 = 90
x = 90 - 18
x = 72
A²-b²=(a-b)(a+b)
so if (x+8) is a factor then (x-8) is also a factor
so
(x+8)(x-8)=x²-8²=x²-64
the blank is 64
The radius is 4 centimeters
