Answer:

78.5714286 cm²

Step-by-step explanation:

The equation for the area of a circle is πr².

You can work out the radius (r) by halving the value of the diameter, which is given as 10cm.

You then square this, so 5² = 25.

Finally, multiply this by pi which is given to you as 22/7.

(22/7) x 25

3.14285714286 x 25 = 78.5714285714, to be exact.

Step-by-step explanation:

What you do to find the answer for these is do a^2+b^2=c^2 Basically meaning 4 × 4 + 3 × 3 will equal a number that you then find the suare root of square root just meaning a number multiplied by itself to equals that number so...

4 × 4 = 16

3 × 3 = 9

16 + 9 = 25

√25 = 5

5 × 5 = 25 therefore c = 5 hope that helps!
