The top of a dining table consisting of a rectangular center measuring 80cm by 35cm, and two semi-circluar ends is shown below. calculator the total distance around it .(perimeter)​

answer: answer is b.

[m < b = 120º]

step-by-step explanation:

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
