Question

I need help with the questions could someone answer them all?

Answer 1

circumference= 40.82 cm

Explanation:

formula circumference= 2 x pi x radius ( 2 x 3.14x 6.5)

3) shaded region = area circle - area rectangle = 132.665 cm - 60 cm^2= 72.665 cm^2

4) 1 foot = 30.48 cm, 6 feet = 182.88 cm = radius 182.88 cm area circle = pi x square radius = 3.14 x 182.88 ^2 ----------> 3.14 x 33445.0944 =105017.5964 cm^2

if 5.49 = 70% , 100% = x so 5.49 x 100 divided 70 = X so X = 7.844 then 5.49 is the 70 % of 7.844

if 6.99 is 36% of something, 6.99 = 36%

X = 100%

so 6.99 x 100 = X (equis) x 36%

6.99 x 100 / 36 = X, so X = 19.416 . 6.99 is the 36% of 19.416
