1. Question Solution

Given The Radius = 8cm

Area of a circle = πr2.

Area of a circle = 3.14 × 8 × 8 [We know, pi (π) = 3.14].

= 3.14 × 64.

= 200.96 square cm or 200.96 cm2.

✔️✔️✔️✔️Answer - 200.96 square cm or 200.96 cm2.

2. Question Solution

4x2(x+2) +3x(5x2+2x-6) -5(3x2-4x).

= 4x3 + 8x2 + 15x3 + 6x2 – 18x – 15x2 + 20x.

= 4x3 + 15x3 + 8x2 + 6x2 – 18x + 20x.

= 19x3 + 14x2 + 2x.

✔️✔️✔️✔️Answer - 19x3 + 14x2 + 2x

☸ Required Answer is ⬇ ⬇⬇ ⬇


⭐ Radius = 8cm

Area = π r²

➡ 3.14 × 8²

➡ 3.14 × 64

➡ 200.96 cm²

Area of circle is 200.96cm²


⭐ Given Equation is

⭕ 4x²(x+2)+3x (5x²+2x-6)-5(3x²-4x)

➡ 4x³ +8x² +15x³ +6x² -18x -15x²+20x

➡ 4x³+ 15x³ +8x²+6x² - 18x+20x

➡ 19x³ +14x²+2x
