8x-10=3x+90
8x-3x= 90+10
5x=100 divide by 5x on each side
X=20
B=3(20)+90= 150
Answers: X=20
Angel B is 150°
Answer:
D - Area = 9/16pi cm²
Step-by-step explanation:
in order to evaluate this question , we will first of all find the radius using the formula for finding the circumference of a circle , we will then find the area of a circle.
<u>solution</u>
given that circumference of a circle = 3/2picm
recall that the formula for finding the circumference of a circle = 2πr
3/2picm = 2πr
multiply through by 2
3picm = 4pir
divide both side by 4pi
3pi cm/4pi = r
r = 3/4 picm
Recall that the Area of a circle = πr²
Area = pi ( 3/4)² cm
Area = 9/16pi cm²
