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

unless if u could do my questions, if not i wouldn't want to

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
