A rectangle has a length of 12 m and a width of 400cm. What is the perimeter of the rectangle?

Answers

Answer 1

Answer:

Answer:

800 + 2400 = 3200

Step-by-step explanation:

Because 12 m = 1200 cm

A = L(2) + W(2)

A = 1200 (2) + 400 (2)

A = 2400 + 800

A = 3200

An automobile engineer is redesigning a conical chamber that was originally specified to be 12 inches long with a circular base of diameter5.7 inches. In the new design, the chamber is scaled by a factor of 1.5.
The volume of the original chamber is
V cubic inches. This i
v cubic inches less than the volume of the new
chamber.

Answers

Answer:

the original volume is lesser than the new volume by 242.47 in³

Step-by-step explanation:

Volume of a cone is;

V = ⅓πr²h

Where;

r is radius

h is height

For the original chamber;

r = 5.7/2 = 2.85 inches

h = 12 inches

Volume of this original chamber is;

V_orig = ⅓ × π × 2.85² × 12

V_orig = 102.02 in³

In the new design, the chamber is scaled by a factor of 1.5.

Thus;

r_new = 2.85 × 1.5 = 4.275 inches

h_new = 12 × 1.5 = 18 inches

V_new = ⅓ × π × 4.275² × 18

V_new = 344.49 inch³

V_new - V_orig = 344.49 - 102.02 =

Thus, the original volume is lesser than the new volume by 242.47 in³
