The lateral area of a right cylinder can be found by multiplying twice the number by a radius on the highway right cylinder has a radius are in hate H written expression that represents the lateral area

AL=2πrh

Step-by-step explanation:

The expression for the lateral area of a cylinder is given as

AL=2πrh

where r is the radius of the circular surface of the cylinder

and h represents the height of the cylinder

while the constant π has a value of 3.142

Now upon substitution we can solve for the lateral area and the unit for the lateral area is (units)^2 i,e cm^2, mm^2 or m^2 etc.

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
