Hope this helps
Sorry if it was late
Easy
leading coefiencet means highest power coefient
degree is the power of the highest exponent
5th degree and leading coefienct is 4
means highest exponet is 5 and the coefienct is 4
means any thing with 4x^5 such that there is no x^n where n>5
4x5 + 3x + 1 is the answer (2nd one)
Answer:
B= 4.6cm
Step-by-step explanation:
A= 
Answer:
a. 16π cm²
b. 24π cm²
c. 33 1/3π cm²
d. 64π-128 cm²
e. 144π-288 cm²
Step-by-step explanation:
To find area of shaded region, find area of whole circle then divide the area where you're left with the area of the shaded region. For the problems with the triangles you find the area of the triangle then subtract that from a fourth of the area of the circle.
Area of a circle = πr²
a.
r=8cm
Area of circle=64π cm²
Shaded region=16π cm²
b.
r=12cm
Area of circle=144π cm²
Shaded region=24π cm²
c.
r=10cm
Area of circle=100π cm²
Shaded region=33 1/3π cm²
d.
r=16cm
Area of circle=256π cm²
Area of triangle=128 cm²
Shaded region=64π-128 cm²
e.
r=24
Area of circle=576π cm²
Area of triangle=288 cm²
Shaded region=144π-288 cm²
