Apedestal is built using a trapezoid shaped base. find the area of the trapezoid.

a = 18 sq m
a= 24 sq m
a= 15 sq m
a= 22 sq m

A = 18 sq m

Step-by-step explanation:

The area of trapezoid is given by :-

, where and b are the opposite parallel sides and h is the height of the trapezoid.

From the picture, a=8 m, b= 4 m and h=3 m

Now, The area of trapezoid is given by :-

Hence, the area of trapezoid A= 18 sq m.

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

answer: sorry i can't you.
