You have to multiply each side by 2.5 then multiply the two new sides to get the answer. So 8 1/2, which is 8.5 is going to become 21.25 and 11*2.5 is going to become 27.50. So the new dimensions are 21.25 and 27.50, you multiply both of them which would give you an area of 584.375. YOU'RE WELCOME :)

Answer:

Area of the new poster = 584.375 inch²

Step-by-step explanation:

Length of old poster = 8 1/2 inches = 8.5 inches

Breadth of old poster = 11 inches

Scale factor = 2 1/2 = 2.5

Length of new poster =  8.5 x 2.5 = 21.25 inch

Breadth of new poster =  11 x 2.5 = 27.5 inch

Area of new poster = 21.25 x 27.5 = 584.375 inch²

Area of the new poster = 584.375 inch²

Jude says that the volume of a square pyramid with base edges of 7 in and a height of 7 in is equal to the volume of a cylinder
irakobra [83]

Answer:

Jude is not correct

Step-by-step explanation:

The volume of a square pyramid is given as:

V = a^2\frac{h}{3}

where a = base edge and h = height

Hence, the volume of the square pyramid with base edge of 7 in and height  of 7 in is:

V = 7^2*\frac{7}{3}

V = 114.3 in^3 ≅ 114 in^3

The volume of a cylinder is given as:

V = \pi r^2h

where r = radius and h = height

Hence, the volume of a cylinder with radius of 7 in and height of 7 in is:

V = \pi *7^2*7

V = 1077.57 in^3 ≅ 1078 in^3

Since their volumes are not equal, Jude is not correct.
