Find the area of a circle with radius, r = 6.89m. Give your answer rounded to 2 DP (2 decimal points)

The photo is attached below

149.14

Step-by-step explanation:

Area of a circle = π

so A = π * 6.89^2 = 149.14 (to 2d.p.)

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
