Area = πr² = π(7)² = 49π.

Area = base × height = 10 cm × 5 cm = 50 cm².

Area = a × b × sin(θ) = 7 m × 4 m × sin(60°) = 28 m² × (√3/2) = 24.5 m².

The area is length * width = 4 * 3 = 12.

Area = 1/2 × (base1 + base2) × height = 1/2 × (8 + 5) × 4 = 26 cm².

Area = (base × height) / 2 = (10 m × 5 m) / 2 = 25 m².

Area = (1/2) × base × height = (1/2) × 4 × 3 = 6 m².

The atomic number is defined as the number of protons in an atom.

The cell is the basic structural and functional unit of life.

The cell is the basic unit of life.

The binary representation of 10 is 1010.

The boiling point of pure water at sea level is 100°C.

The boiling point of water at sea level is 100°C.

Neutrons have no charge; they are neutral particles found in the nucleus of an atom.

A proton has a positive charge of +1.

The decimal equivalent of the binary number 11001 is 25.

The decimal equivalent of the hexadecimal number 1A is 26.

The degree of a polynomial is the highest power of x. Here, the highest power is 4.

Using the distance formula: d = √((x2 - x1)² + (y2 - y1)²) = √((7 - 3)² + (1 - 4)²) = √(16 + 9) = √25 = 5.

Regular physical activity increases basal metabolic rate (BMR) and total daily energy expenditure (TDEE) due to increased muscle mass and metabolic activity.

Standard form of a circle: (x - h)² + (y - k)² = r², where (h, k) is the center and r is the radius. Thus, (x - 2)² + (y + 3)² = 5² = 25.

Using point-slope form: y - y1 = m(x - x1) => y - 1 = 2(x - 1) => y = 2x - 2 + 1 => y = 2x - 1.

The hexadecimal equivalent of the decimal number 255 is FF.

The jelly-like substance inside the cell is called cytoplasm.

Lateral surface area of a cylinder = 2π * radius * height = 2π * 2 * 10 = 40π cm².

Arc length = (θ/360) * 2πr = (60/360) * 2π(5) = (1/6) * 10π = 5π/6 m.

Using the Pythagorean theorem: d = √(length² + width²) = √(6² + 8²) = √(36 + 64) = √100 = 10.

Using the Pythagorean theorem, c² = a² + b². Thus, c² = 6² + 8² = 36 + 64 = 100, so c = √100 = 10 cm.

Using the distance formula: d = √((3 - (-1))² + (3 - (-1))²) = √((4)² + (4)²) = √(16 + 16) = √32 = 4√2.

Nervous tissue is characterized by its ability to transmit impulses.
