Question

Find the area of a circle with radius, r = 58cm.
Give your answer rounded to 3 SF​

Answer 1

Here we are given with the radius of a circle and we have to find the area using formula.

✤ Formula for finding area of a circle:

`\large{ \boxed{ \sf{\red{Area \: of \: \circ = \pi {r}^(2) }}}}`

Where r is the radius of the circle. So let's plug in the values for finding the area of the circle:

➝ Area = π(58 cm)²

➝ Area = 3.14 × 58 cm × 58 cm

➝ Area = 10562.96 cm²

Now let's round off upto 3 significant figures: 10600 cm² (Answer)

Answer 2

The answer is 10600 cm²

Explanation:

Area of a circle = πr²

where

r is the radius of the circle

From the question

r = 58 cm

The area of the circle is

A = 58²π

= 3364π

= 10568.3176866761...

We have the final answer as

10600 cm² to 3 significant figures
