Can someone help me and please explain how you did it

Radius: 7

Diameter: 14

Area Formula: π r^2

Area 154 ft^2

Step-by-step explanation:

Radius: 14/2 = 7

The radius is always half the diameter.

Area Work

A = π(7)^2

A = π(49)

A = 153.9380 ft^2

hello i am doing good for you that it's summer in your country or state ; )

btw in my country we just have sun and rain as (because i live in the caribbean lol)

also, thx a lot for the points : )

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
