The diameter of a building's dome is 82 feet at its widest point. Find its circumference. Round to the nearest tenth. Use 3.14 for π.

d = 82 ft.

The circumference of the dome is
ft.

257.5 ft

Step-by-step explanation:

circumference of a circle with diameter=

pi*d

3.14*82=257.48

Hope this helps!

257.5 feet

Step-by-step explanation:

A dome is circular in shape, therefore Circumference of the dome is the circumference of a circle which is calculated by

= 2 pi r

Given

Diameter = 82 feet

Radius r = diameter/2 = 82/2

= 41

Pi = 3.14

Therefore

Circumference = 2 x 3.14 x 41

= 257.48

= 257.5 feet

based on context clues you gave i'm assuming the answer would be c.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
