Kiley would need glass of area between 3.14 and 12.56 square feet
Step-by-step explanation:
The Circumference of the circle is given by 2πr where “r” is the radius
Range of the circle’s circumference- 6.28 feet to 12.56 feet
Considering lowest radius as r₁ and the largest as r₂
2πr₁= 6.28
∴r₁= 6.28/(3.14*2) = 1 feet
Similarly
⇒2πr₂=12.56/(3.14*2)=2 feet
We know that area of the circle is given by πr
²
Area of the circle= 3.14*(1)² = 3.14 square feet
Area of the largest radius= 3.14*(2)²= 12.56 square feet
Hence Kiley would need glass of area between 3.14 and 12.56 square feet
Answer:
u can find the volume by using formula 1/3×π×r^2×h
In the given question,
1/3×3.14×23^2×15
=8305.3
B, just because the diagonals are perpendicular doesn't mean they are equal in length, you can get a Kite with perpendicular diagonals
5x + 2y = 6
3x + y = 4....multiply by -2
-------------
5x + 2y = 6
-6x - 2y = -8 (result of multiplying by -2)
-------------add
-x = -2
x = 2
5x + 2y = 6
5(2) + 2y = 6
10 + 2y = 6
2y = 6 - 10
2y = -4
y = -4/2
y = -2 <=== here it is
