Given the radius (r) is 5 centimeters, we can plug the value into the formula: Surface area = 4 * π * (5^2) Surface area = 4 * π * 25 Surface area = 100π The surface area of the sphere is approximately 314.16 square centimeters.,The surface area of a sphere with a radius of 5 centimeters can be calculated using the formula: Surface Area = 4 * π * r² where r is the radius. Plugging in the given value: Surface Area = 4 * π * (5 cm)² Surface Area = 4 * π * 25 cm² Surface Area ≈ 314.16 cm² So, the surface area of a sphere with a radius of 5 centimeters is approximately 314.16 square centimeters., The surface area of a sphere is calculated using the formula: Surface Area (SA) = 4 * π * r^2 where r is the radius of the sphere. In this case, the radius is 5 centimeters. So, SA = 4 * π * (5 cm)^2 = 4 * π * 25 cm^2 = 100 * π cm^2 = 314.16 cm^2 (approximately) So, the surface area of the sphere with a radius of 5 centimeters is approximately 314.16 square centimeters.

answer:To find the perimeter of the trapezium, we need to add the lengths of all four sides. We are given the lengths of the base (12 cm), top edge (8 cm), and the two non-parallel sides (5 cm each). Perimeter = Base + Top edge + Non-parallel side 1 + Non-parallel side 2 Perimeter = 12 cm + 8 cm + 5 cm + 5 cm Perimeter = 30 cm The perimeter of the trapezium is 30 cm.,To find the perimeter of the trapezium, we need to add the lengths of all its sides. The question provides the base (12 cm), top edge (8 cm), and two non-parallel sides (each 5 cm). Perimeter = base + top edge + non-parallel side 1 + non-parallel side 2 Perimeter = 12 cm + 8 cm + 5 cm + 5 cm Perimeter = 30 cm The perimeter of the trapezium is 30 cm., To find the perimeter of a trapezium, we need to add up the lengths of all its sides. In this case, the trapezium has two non-parallel sides, a base, and a top edge. We are given: Base (b) = 12 cm Top edge (a) = 8 cm Non-parallel sides (c, d) = 5 cm each The formula for the perimeter of a trapezium is: Perimeter = a + b + c + d Substituting the given values into the formula, we get: Perimeter = 8 cm + 12 cm + 5 cm + 5 cm Perimeter = 30 cm So, the perimeter of the trapezium is 30 cm.
