Question

find diameter,area, circumference
1) r=2.6 CM
2) r=5.4 CM
3) r= 6.8 CM
4) r= 12.26 CM​

Answer 1

Answer:

formula lagao answer miljaega.

• diameter = R/2
• area = pi(r)²
• circumference = 2(pi)(r)

Answer 2

Step-by-step explanation:

1)given that r=2.6cm

diameter=2r

d=2(2.6)

d=5.2cm

Area=3.14*2.6*2.6

=21.2264cm2

circumference=2(3.14)2.6

=16.328cm

2)given that r=5.4cm

diameter=2r

=2(5.4)

=10.8cm

Area=3.14(5.4)(5.14)

=91.5624cm2

circumference=2(3.14)(5.14)

=32.2792cm

3)r=6.8cm

d=2r

=2(6.8)

=13.6cm

Area=3.14(6.8)(6.8)

=145.1936cm2

circumference=2(3.14)6.8

=42.704cm

4)r=12.26cm

d=2r

=2(12.26)

=24.52cm

Area=3.14(12.26)(12.26)

=471.965864cm2

circumference=2(3.14)(12.26)

=76.9928cm
