Area=

Step-by-step explanation:

Area of any circle can be find with the help of the formula:

If the radius of the circle is given then its area can be find by putting 'r' in the formula.

We have given the radius of the circle= 7 units

So, the expression for the  area of the circle with radius= 7 units is:

                     Area=

                         '' is a constant have a fixed value of  

So, area of the circle =

Area=

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
