Answer:
Step-by-step explanation:
r = 7 cm
h = 15cm
pi = 3.14
Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).
Area = 2* pi *r^2 = 2 * 3.14 * 7^2
Area = 2 * 3.14 * 49
Area = 307.72 Don't round this.
Cylinder body
Cylinder body = Circumference * h = 2*pi * r * h
Cylinder body = 2* 3.14 * 7 * 15
Cylinder body = <u> 659.4</u>

Answer:
16.07 milligrams
Step-by-step explanation:
From the question,
Using the formula of radioactive decay,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.
Make R' the subject of the equation
R' = R/(2ᵃ/ᵇ)................ Equation 2
Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days
Substitute these values into equation 2
R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)
R' = 100/(6.222)
R' = 16.07 milligrams of plonium-210
Answer:
15
Step-by-step explanation:
The product of the prime factors of 3375 are
3375 = 3³ × 5³, then
![\sqrt[3]{3375}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3375%7D)
= ![\sqrt[3]{3^3(5^3)}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3%5E3%285%5E3%29%7D)
= ![\sqrt[3]{3^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3%5E3%7D)
× ![\sqrt[3]{5^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%5E3%7D)
= 3 × 5
= 15
