Question 7:
Diameter = 6.2 cm so Radius = 3.1 cm
A=πr² = 3.14 × 3.1² = 30.1754 cm² = 30.18 cm²
Question 8:
Circumference = 2πr
16π = 2πr
therefore 16 = 2r so r = 8cm
Short answer: No
Explanation: if you bring the fractions down as low as possible, the first bag has a 1 in 4 chance of getting a red marble. The 2nd bag can't be brought down anymore because 26 and 7 do not share any common divisors.
Answer: the quotient will be equal to 23
The equation to calculate what divided by 23 equals 1 is as follows:
X/23 = 1
Where X is the answer. When we solve the equation by multiplying each side by 23, you get get:
X = 23
Therefore, the answer to what divided by 23 equals 1 is 23
so the quotient will be equal to 23
