The calculation for circumference is 2πr or 2 × π (pi=3.14) × radius of a circle

Since the diameter of this circle is 7cm, and the radius is half of the diameter, 7 ÷ 2 = 3.5

So, 2×3.14(π)×3.5=21.98

Answer:

see explanation

Step-by-step explanation:

(a)

To change a mixed number to an improper fraction

Multiply the whole number by the denominator of the fraction and add the numerator. This value is the numerator of the improper fraction while the denominator remains unchanged, that is

(2 × 13) + 12 = 26 + 12 = 38 ← numerator

2 $\frac{12}{13}$ = $\frac{38}{13}$

(b)

To change an improper fraction to a mixed number

divide the numerator by the denominator, noting the remainder, which forms the numerator of the fraction in the mixed number.

$\frac{47}{19}$ = 2 remainder 9, hence

$\frac{47}{19}$ = 2 $\frac{9}{19}$

Consider the triangle below. Determine the angle measure for the bottom two angles in order for the triangle to be classified as

FinnZ [79.3K]

Answer:

The angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle are 30 degrees each

Explanation:

An isosceles triangle has two of its angles equal.

Given that one angle is 120 degrees, assuming the remaining angles are equal, since the sum of the angles in a triangle is 180 degrees, we have:

120 + x + x = 180

120 + 2x = 180

2x = 180 - 120 = 60

x = 60/2 = 30

Each of the remaining angles measure 30 degrees
