Assuming that you mean s = 1/4.
A = 80s^2
A = 80(1/4)^2
A = 80(1/16)
A = 5 square units.
Answer:
Well, the tank's volume is 1.2 x 1.2 x 1.35 = 1.944 m³ = 1944 litres.
It is half-full, so it contains 1944 / 2 = 972 litres of water.
That is enough to fill 972 / 9 = 108 9-litre buckets.
Step-by-step explanation: h = height of water = 1.35 m/2 = 0.675 m
A = area of tank = s² = (1.2 m) = 1.44 m²
V = volume of water
V = Ah = (1.44 m²)(0.675 m)
1. Log7 (49)=2
2. Log63(216)=3
3. Log2 (256)=8
4. Log4 (64)= 3
5. Log5 (3125)=5
Completing the squares, the correct statements regarding the equation of the circle are given by:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
<h3>What is the equation of a circle?</h3>
The equation of a circle of center and radius r is given by:
In this problem, the equation is given by:
x² + y² - 2x - 8 = 0.
Completing the squares:
(x - 1)² + y² = 8 + 1²
(x - 1)² + y² = 9.
Hence the center is (1,0), the radius is 3, and the correct statements are:
- The radius of the circle is 3 units
- The center of the circle lies on the x-axis.
- The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
