1. find the area of the given circle. round to the nearest tenth.

2. find the circumference of the given circle. round to the nearest tenth.

3. find the area of the given circle. round to the nearest tenth.

4. find the area of the irregular shape. round to the nearest tenth.

5. find the area of blue proportion of the irregular shape. round your answer to the nearest tenth.

(all the answers and questions are in the pictures. if you’d like me to write the answers in the comments because you can’t see, let me know. otherwise, with these 5 questions. first answer will get brainliest if correct) (tysm)

1. area = 3.14 x 3.5^2 = 38.46 = 38.5 cm^2

2. circumference = 2 x 3.14 x r = 21.98 = 22.0 cm

3. area = 3.14 x 6^2 = 113.04 = 113.0 ft^2

4. area = (8*5) + (.5x 3.14*4^2) = 90.24 = 90.2 cm^2

5. area = (4*4) - (3.14x 2^2) = 3.44 = 3.4 in^2

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
