Answer:
471.24 squared inches
Step-by-step explanation:
The formula of surface area of a cylinder is:
A=2πrh+2πr²
------------------------------------------------------------------------------------------------------------
So when we plug in our numbers:
2 × π × 5 × 10 + 2 × π × 25 = 471.24

Answer:
Perimeter, P = (24d+0.8) cm
Step-by-step explanation:
Given that,
Width of rectangle, B = (4.4d−4.3) cm
Length, l = (7.6d+4.7)
Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,
Perimeter = 2(L+B)
P = 2[(7.6d+4.7)+(4.4d−4.3)]
Collecting like terms
P = 2[(7.6d+4.4d)+(4.7−4.3)]
P=2(12d+0.4)
⇒ P = 24d+0.8
So, the expression for the perimeter of the rectangle is (24d+0.8) cm.
