Answer:
36
Step-by-step explanation:
To get 1/4 of 48 we have to divide 48 by 4
48 ÷ 4 = 12
To get 3/4 of 48 we multiply 12 by 3
12 × 3 = 36
Answer:
3) B. 77 flowers
4) A. 62.8
Step-by-step explanation:
3) First find the area. The area of a circular flower bed is found using the formula for a circle A = πr². Here the diameter is 14 so r =7.
Substitute r = 7.
A = π(7)² = 49π = 153.86 square feet.
Each flower requires 2 square feet.
Divide the area by 2 for the number of flowers.
153.86 / 2 = 76.93 = 77
4) First find the area of the entire circle. The area is found using the formula for a circle A = πr².
Substitute r = 6.
A = π(6)² = 36π = 113.04 square feet.
Now find the area of the small circle inside. Then subtract the two areas.
The area is found using the formula for a circle A = πr².
Substitute r = 4.
A = π(4)² = 16π = 50.24 square feet.
The shaded area is 113.04 - 50.24 = 62.8.
