Question 5 options: What is the approximate area of a circle with a radius of 11 cm? Use 3.14 for π. ______ cm2
kobusy [5.1K]

The area of circle is 379.94 cm².

Step-by-step explanation:

Given,

Radius of circle = 11 centimeters

We have to calculate the area of circle.

We know that;

Area of circle = \pi r^2

Here;

π = 3.14 , r = 11

Area of circle = 3.14*(11)^2

Area of circle = 3.14*121

Area of circle = 379.94 squared centimeters

The area of circle is 379.94 squared centimeters.

Keywords: area, circle

A 4.3 ounce tomato has about 24 calories. How many calories are in one ounce ?
mafiozo [28]

Answer: approximately 5.5814 calories

==================================

We start off with this ratio

4.3 ounces : 24 calories

Divide both parts of the ratio by 4.3 so that we end up with 1 ounce on the left side

4.3 ounces : 24 calories

4.3/4.3 ounces : 24/4.3 calories

1 ounce : 5.5814 calories

This value is approximate to four decimal places.
