Answer:
A) 2
Step-by-step explanation:
It shows it in the formula.
Answer:
R=22
Step-by-step explanation:
180-44= 136
136÷2= 68
90-68= 22
180 is angle of the straight line. 44 is subtracted to get angle of only the triangle on the left which is 136. 136 is then divided by 2 since the remaining two angles are equal and you'll get 68. R is part of a right-angled triangle (90°) subtract 68 from that and you will get 22
Answer:
5 in.
Step-by-step explanation:
Given that
b1 = 12
b2 = 8
A = 50
Formula is (1/2)h(b1 + b2), on substituting
50 = 1/2 * h(12 + 8)
50 = 1/2 * h(20)
100 = 20h
h = 100/20
h = 5
The height is 5 in
Step-by-step explanation:
Area of Sector
= θ/360° * πr² (degrees) or 0.5r²θ (radians)
Question 11:
- (88°)/360° * π(19)² = 277.23ft².
Question 12:
- (260°)/360° * π(11)² = 274.54mi².
Question 13:
- 0.5(6.2)²(7π/12) = 35.22km².
Question 14:
- 0.5(7.1)²(5π/3) = 131.97cm².
Question 15:
- (215°)/360° * π(4.5)² = 37.99yd².
Question 16:
- 0.5(21.4)²(13π/18) = 519.54m².
