Find the area of the shape

14 units²

Step-by-step explanation:

The area of the shape = area of a triangle

Area of triangle = ½ × base × height

base = 7

height = 4

Plug in the value into the formula:

Area = ½ × 7 × 4

Area = ½ × 28

Area = 14 units²

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
