Answer:
The diameter of the pizza = 14 in
Radius of the pizza = (14/2)in = 7in
Area of a whole pizza =
πr^2
=( 22/7 × 7^2)in^2
=( 22/7 × 49)in^2
154 in^2
Area of a half pie =( 1/2 × 154)in^2 = 77in^2
Area of one of 8 slices = (1/8 × 154)in^2 = 19.25in^2
Hope it helps
Answer:
(a) 0.198 cm/s (b) 1 cm/s
Step-by-step explanation:
It is given that,
The rate of change of area of a cicle,
(a) The area of a circle is given by :
Differentiate both sides,
(b) Circumference, = 5 cm
Hence,
(a) 0.198 cm/s (b) 1 cm/s
Answer:
y=5
x=7
Step-by-step explanation:
When given an expression in the form a⁻ᵇ the expression is the same as 1/aᵇ where a and b are integers.
Solving the question by giving the equivalents of the expression:
Therefore (-j)⁻⁷ is the same as 1/j⁷
The value of x=7
k⁻⁵+m⁻¹⁰=1/k⁵+1/m¹⁰
Therefore the value of y is 5.
Simplify to
Both are over 11, so, just sum.
