For question one, you would need to use the formula pi r ^2. So first you have 4.5, which is your radius(stands for r). Then you square it, which is 20.25. Then, you multiply 20.25 with pi. Then for circumference, you do 2 x pi x the radius which is 4.5. So for area, you get 63.62. Then for circumference you get 28.27.
For question 2, it is basically the same steps but instead you a diameter, not a radius. To get the radius, divide by 2, which the radius will be 6. Then from there, the radius is 6, and you solve the question.
Answer:
33%
Step-by-step explanation:
16 is one third of 48
Do a ratio tall over shadow. How tall is tree / shadow. How tall is person / shadow then cross multiply. X/7.5 =5/3. 37.5=3x. Divide by 3 answer 12.5
Step-by-step explanation:
1. Do 1022÷2 to get the base number (511)
2. Multiply based number by 3 to get 'no' votes (1533)
3. add 'yes' votes to the 'no' votes(2555)

Answer:
The multiplicative inverse of y is
.
Step-by-step explanation:
Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.
Let the multiplicative inverse of y be represented by a, so that;
a x y = 1
ay = 1
divide both sides by y to have,
a = ![\frac{1}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7By%7D)
Thus, the multiplicative inverse of y is
.
This is applicable to any given value. Examples:
i. Given 2, the multiplicative inverse is
.
⇒ 2 x
= 1
ii. What is the multiplicative inverse of 5?
The required answer is
.
