The surface area of a polyhedron can be found by: A. multiplying the perimeter of the base by the height and adding the area of both bases.
B. adding the lateral surface area to the height C. multiplying the perimeter of the base by the length and adding the lateral surface area.
D. adding the total volume to the area of one of the bases.

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.

answer: what do you mean

it is true

step-by-step explanation:

all the combinations add up i used   calculator

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
