Manuel incorrectly claimed that the surface area of the cylinder

shown is about 621.7 in.. Use a formula to find the surface area of the cylinder.

Use 3.14 for it. What was his likely error?

11 in

The surface area of the cylinder is about

(Round to the nearest tenth as needed.)

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
