530.66 mm²

5.3066 cm²

Step-by-step explanation:

A = π·r²

= 3.14×(13mm)²

= 3.14×169mm²

= 530.66 mm²

= 5.3066 cm²

Answer:

530.66mm²

Step-by-step explanation:

Area of a circle = \pi r^{2}

r(radius) = 13mm

Area = (3.14 × 13²)mm²

        = (3.14 × 13 × 13)mm²

        = (3.14 × 169)mm²

        = 530.66mm²

Hope this helps :))

Set up an algebraic equation that could represent the following situation:
UkoKoshka [18]

Answer:

The profit for any purchased of bananas is R2.

Step-by-step explanation:

Cost of 1 kg banana = R 3

Banana purchased = 4 kg

So, the cost of 4 kg bananas = 4 x 3 = R 12

Amount paid = R 14

Profit = R 14 - R 12 = R 2

So, the profit on any purchased of bananas is R 2.

Solve for x. x3 = 216
vampirchik [111]
I'm assuming the equation is x^3 = 216 or x^3 = 216 (both mean the same thing)

If so, then the solution to x^3 = 216 is x = 6

<span>We can find this by taking the cube root of both sides
</span>x^3 = 216
x = 216^(1/3) .... 1/3 power means cube root
x = 6

Checking the answer:
x^3 = 216
6^3 = 216
6*6*6 = 216
216 = 216
Answer is confirmed

So once again the answer is x = 6. This is assuming the initial assumption made at the top of the problem holds up.
