Find the area of the shape.
Either enter an exact answer in terms of π or use 3.14 for π and enter your answer as a decimal.

A = pi

   = 3.14

Step-by-step explanation:

We have 1/4 of a circle

The area of a circle is given by pi r^2

The area of this quarter circle is

A = 1/4 pi r^2

The radius is 2

A = 1/4 pi (2)^2

A = 1/4 pi (4)

A = pi

We can use 3.14 for pi

A = 3.14

the answer is 11.2 (i know i’m late)

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
