A pan of brownies is 7/10 full. Tyreese buys 2/5 of the brownies. a. Draw a picture of how the brownie pan looks before and after Tyreese buys his brownies.

b. What fraction of a whole pan of brownies does Tyreese buy?

the answer is 9/10

Step-by-step explanation:

I cant draw sorry(┬┬﹏┬┬)╰(*°▽°*)╯

The formula for circumference of a circle is C = 2πr where C is the circumference and r is the radius. The formula for area is A = πr^2 where A is the area and r is the radius. Thus, we need to find r to find the correct area:

C = 2πr

65π = 2πr

r = 32.5

Now we plug this result into the area formula:

A = π(32.5)^2

A = 1056.25π 

So, the answer is D.
