20/30 or you can put it down as 6 2/3 or 6.6
- Factoring a quadratic equation can be defined as the process of breaking the equation into the product of its factors.
- Factorize the equation by breaking down the middle term.
- Let’s identify two factors such that their sum is 7 and the product is -18.
Sum of two factors = 7 = 9 - 2
Product of these two factors = 9 × (-2) = 18
- Now, split the middle term.
- Take the common terms and simplify.
Thus, (3x - 1) and (2x + 3) are the factors of the given quadratic equation.
- Solving these two linear factors, we get
Answer:
Area of plane surface of cylinder = 2772 sq.cm.
Step-by-step explanation:
Let r be the radius and h be the height of the cylinder.
Curved Surface Area = 1848 sq.cm
2πrh = 1848
2××rh = 1848
rh = 1848 × ×
rh = 294
Sum of radius and height = 35
r + h = 35 --- (1)
Now,
r - h =
=
=
=
= 7
r - h = 7 --- (2)
Adding (1) and (2),
2r = 42
r = 21 cm.
Area of the plane surface = 2 × π
= 2 × × 21 × 21
= 2772 sq.cm.
