Answer:
Below.
Step-by-step explanation:
The area = the height (h) times the base.
So Q2:
21 = h * 7
h = 21/7 = 3
55 = b * 5
b = 11.
18.75 = h * 7.5
h = 18.75 / 7.5
= 2.5.
Step-by-step explanation:
circumference of a circle
2×pi×r
area of a circle
pi×r²
r = 8 yd
circumference is
2×3.14×8 = 3.14×16 = 50.24 yd
area is
3.14×8² = 3.14×64 = 200.96 yd²
