Answer:
78.10 cm^2
Step-by-step explanation:
The area of the shaded region is the area of the rectangle subtracted from the area of the circle.
area of circle = (pi)r^2
area of rectangle = LW
shaded area = area of circle - area of rectangle
shaded area = (pi)r^2 - LW
shaded area = (pi)r^2 - LW
shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)
shaded area = (3.14159)(36 cm^) - 35 cm^2
shaded area = 113.097 cm^2 35 cm^2
shaded area = 78.097 cm^2
Answer: 78.10 cm^2
Answer:
Step-by-step explanation:
No. of blue n(B) = 5
No. of red n(R) = 3
Total marble is N = 8
P(R) = n(R)/N
= 3/8
Answer:
The coefficient is 7
Step-by-step explanation:
The coefficient of an algebraic expression is the number that is being multiplied by a variable or multiple variables. In this case, 7 is being multiplied by x and y, so 7 is the coefficient.
Cosa/1+sina + 1+sina/cosa = (cos^2a+1+2sina+sin^2a)/(cosa)((1+sina)
=( 1+1+2sina)/(cosa) (1+sina)
=2(1+sina)/ (cosa) (1+sina)
=2/cosa
=2sec a (verified)
