Answer:
7 cm²
Step-by-step explanation:
First, find the area of the big circle with the formula A = r²
A = (3)²
A = 9
Now, we can find the areas of the smaller circles. Since they have the same radius, they are congruent (will have the same area)
A = r²
A = (1)²
A =
Now, we will subtract the areas of the smaller circles from the area of the big circle to find the area of the shaded region:
9 -
-
= 7
So, the area of the shaded region is 7 cm²
Answer:
1200
Step-by-step explanation:
Find the width and the height show in the picture then use the formula Area = length X height
The width is 40 and the height is 30. Therefore Multiply it together and get 1200

complete question:
A mini game cube is covered in different colors and has a side length of 1.8 inches. Which of the following would represent the amount of space covered in various colors?
A. 116.64 in2
B. 3.24 in2
C. 19.44 in2
D. 10.8 in2
Answer:
C. 19.44 in2
Step-by-step explanation:
A cube is a 3 dimensional figure bounded by 6 square faces. All the sides of a cube are equal in length. The picture below is a cube. The amount of space covered in different colors will be the surface area of the cube.
surface area = 6L²
where
L = length
L = 1.8 inches
surface area = 6 × 1.8²
surface area = 6 × 3.24
surface area = 19.44 inches²
Solution: We are given:
ACT scores follow normal distribution with
SAT scores follow normal distribution with
Now, let's find the z score corresponding to Joe's SAT score 1351.
Therefore, Joe's SAT score is 1.56 standard deviations above the mean.
Now, we have find the Joe's ACT score, which will be 1.56 standard deviations above the mean.
Therefore, we have:
Therefore, Joe's equivalent ACT score to SAT score 1351 is 28.4
