Area = πr². 154 = (22/7)r². Solving gives r² = 154 * 7 / 22 = 49, so r = 7 cm.

Area = πr^2 => 36π = πr^2 => r^2 = 36 => r = 6.

Area = πr^2 => 50π = πr^2 => r^2 = 50 => r = √50 = 5√2.

Area = πr²; 78.5 = π * r²; r² = 78.5/π = 25; r = 5 cm.

Magnetic flux (Φ) is given by the product of magnetic field (B) and area (A). If the area is doubled and the magnetic field remains constant, the magnetic flux also doubles.

Magnetic flux (Φ) is given by Φ = B * A. If the area (A) is doubled and the magnetic field (B) remains constant, the magnetic flux also doubles.

Magnetic flux (Φ) is given by Φ = B * A. If the area (A) is doubled, the magnetic flux also doubles.

Magnetic flux Φ is given by Φ = B * A. If the area A is doubled while B remains constant, the magnetic flux also doubles.

Induced EMF is proportional to the area of the loop. If the area is doubled, the induced EMF also doubles.

Area = base × height. Thus, 120 = 15 × height, giving height = 120/15 = 8 units.

If the height of a parallelogram is halved, the area is also halved, as area = base × height.

This formula applies to a kite, where the diagonals intersect at an angle.

In the formula for the area of a quadrilateral, d1 and d2 represent the lengths of the diagonals.

Area = Length * Width. Therefore, Width = Area / Length = 48 / 8 = 6 meters.

Area = Length × Width. Therefore, Width = Area / Length = 48 / 8 = 6 units.

Relative error = (absolute error / measured value) = 0.5 / 30 = 0.0167.

Uncertainty in area = 2 * length * uncertainty in length = 2 * 10 * 0.1 = 2 m².

Area of a sector = (θ/360) × πr². Thus, 25π = (θ/360) × π(10)². Solving gives θ = 90 degrees.

Area of a sector = (θ/360) × πr². Thus, 25π = (θ/360) × π(5)². Solving gives θ = 90°.

Area of a sector = (θ/360) × πr². Thus, 30 = (θ/360) × π × 25. Solving gives θ = (30 × 360)/(25π) ≈ 72°.

Area of a square = side². Therefore, side = √64 = 8 cm.

Area = (1/2) × (base1 + base2) × height. Thus, 60 = (1/2) × (10 + 20) × height, giving height = 60 / 15 = 4 units.

Area = (1/2) × (base1 + base2) × height. Thus, 60 = (1/2) × (10 + 20) × height, giving height = 60 / 15 = 4 units.

Area = 1/2 * base * height. Therefore, 24 = 1/2 * 8 * height, which gives height = 6 cm.

The area of a triangle is given by the formula Area = 1/2 * base * height. Thus, 24 = 1/2 * 8 * height, which gives height = 6 cm.

Area = 1/2 * base * height. Thus, 30 = 1/2 * 10 * height. Solving gives height = 6 cm.

Area = 1/2 * base * height => height = 30/(1/2 * 10) = 6.

Area = 1/2 * base * height, so 48 = 1/2 * 12 * height, height = 48/(6) = 8 cm.

Area of a triangle = (1/2) × base × height. Thus, 50 = (1/2) × 10 × height. Solving gives height = 10 units.

The area of a triangle is given by (1/2) * base * height. Thus, 60 = (1/2) * 10 * height. Solving for height gives height = 12 units.
