Step-by-step explanation:
A = pi × r²
A = pi × 13²
A = 530.93 km²
Answer: A, B, D
A, B, and D are equations because an equation has an equal sign that connects two expressions together (i.e., equations have equal signs). In this case, only A, B, and D have equal signs.
Answer:
38.105
Step-by-step explanation:
The area of this triangle = 0.5 * b * c * sin(A)
= 0.5 * 11 * 8 *sin(60) sin(60) = 
= .866025...
= 0.5 * 11 * 8 * .866025
= 38.105
Answer:
803.84 bc radius is half of diameter which is 16
Area of circle is (pi)r^2 = (3.14)16^2= 3.14 x 256 = 803.84
Step-by-step explanation:
The number 35.4 when rounded to the nearest tenth is 5.4
