Find the circumference of a circle whose radius is 15.4cm

LenaWriter [7]

$r=15,4\ cm\\C=2\cdot\ \pi\ \cdot\ r\\C=2\cdot\ \pi\ \cdot\ 15,4\ cm\\C=30,8\ \pi\ cm$

$\pi\approx\ 3,14$

$C=30,8\ \cdot\ 3,14\ cm\\C=96,712\ cm$

PLEASE HELP

Ronch [10]

Answer:

1 and 5

Step-by-step explanation:

The squares have a side length of 10 and 1 square side is the radius of the half-circles. Since there are two half-circles, find the circumference for one full circle:

$C=2\pi r$

Insert the radius:

$r=10\\C=2\pi *10$

Simplify pi:

$C=2*3.14*10$

Simplify multiplication:

$C=6.28*10\\C=62.8$

The circumference of the circles is 62.8. Now find the perimeter of the exposed squares with side length 10. There are 4 exposed sides, which equals one square. Find the perimeter:

$P=10+10+10+10\\P=10+10+20\\P=10+30\\P=40$
