Measurement formulas

Convert 10 meters to kilometers

• 10 m = 0.01 km

• 10 m = 10,000 km

• 10 m = 1 km

• 10 m = 0.1 km

Convert 118 mm to cm

• 118 mm = 1.18 cm

• 118 mm = 0.118 cm

• 118 mm = 11.8 cm

• 118 mm = 0.0118 cm

2.5 km is how many meters?

• 2.5 km = 25 m

• 2.5 km = 0.0025 m

• 2.5 km = 2.500 m

• 2.5 km = 2500 m

• True

• False

Calculate the perimeter of the rectangle. Length is 6 cm and width is 5 cm.

• 6 + 6 + 5 + 5 = 22 cm

• 6 x 5 = 30 cm

• 6 + 5 = 11 cm

• 2l + 2w = 2 + 6 + 2 + 5 = 15 cm

Calculate the perimeter of the hexagon if each side is 2 cm.

• 2 + 6 = 12 cm

• 2 x 4 = 8 cm

• 6 cm x 2 = 12 cm

• 6 cm x 2 cm = 12 cm²

Calculate the circumference of a circle with radius 4.2 cm.

• 2 x π x 4.2 = 26.4 cm²

• π x 4.2² = 55.4 cm

• π x 4.2² = 55.4 cm²

• 2 x π x 4.2 = 26.4 cm

Calculate the circumference of a circle with a diameter of 15 cm.

• 2πr = 2 x π x 15 = 94.2

• πd = π x 15 = 47.1 cm

• π x 15² = 706.9 cm

• 15² = 225 cm

The formula for the circumference of a circle is

• π x radius²

• 2πr or, πd

• Only πd

• π x radius

The area of the rectangle is

• 5 + 8 = 13 cm

• 5 + 8 = 13 cm²

• 5 x 8 = 40 cm

• 5 x 8 = 40 cm²
