Answer:
d = 24
Step-by-step explanation:
The area of a circle is given by A = π * r²
We are told the area of the clock is 144π.
Let's clear the formula for the radius:
r² = A / π
r² = 144π / π
r² = 144
r = √144
r = 12
The diameter is two times the radius, d = 2r = 2*12 = 24.
From the following choices, the correct step in evaluating: ∫ cos2 5x dx is 1 - cos 10x / 2dx.
The sum of two numbers is 136 (sum is what you get when you add two numbers together). If one of the two numbers is 51, and the other number is X, then:
X + 51 = 136
To solve for x we subtract both sides by 51.
X + 51 -51 = 136 - 51
X = 85
The other number is 85.
What are the common factors of these two numbers?
Factors are the numbers that multiply to make the product.
Factors of 51: 1, 51, 3, 17
Factors of 85: 1, 85, 5, 17
