84. Area of a triangle is (base x height) / 2
Answer:
13/20
Step-by-step explanation:
65%=65/100
65/100=13/20
B has to be 70° and A has to be 115° so I’m confused by your options
Circumference = 2(pi)r
Area = (pi)r^2
r = 5
5 * 2 = 10
Circumference = 10π
5 * 5 = 25
Area = 25π
Using 3.14 as pi substitute:
5 * 3.14 = 15.7
15.7 * 2 = 31.4
Circumference = 31.4
5 * 5 = 25
25 * 3.14 = 78.5
Area = 78.5
Try x = 65
