Step-by-step explanation:
a=31
b=27
A = 46 degree
now, Area of ️ABC =ab siny÷2
=31×27 sin46÷2
=301.04371 .
Answer:
C
Step-by-step explanation:
The figure consists of a semicircle of radius 6 m, and a triangle with base of 12 m and height of 5 m. The base of the triangle is 12 m since it has the length of the diameter of the circle, or twice the 6-m radius.
A = area of semicircle + area of triangle
A = (1/2)πr² + bh/2
A = (1/2)π × (6 m)² + (12 m)(5 m)/2
A = (18π + 30) m²
Answer: C
Answer:
3
Step-by-step explanation:
- 4x + 1 = - 11
- 4x = - 11 - 1
- 4x = - 12
x = - 12 / - 4
x = 3
